Revised version of a paper presented at the Conference "The Distribution of Economic Well-Being in the 1980s - an International Perspective", June 21 - 23, 1993, in Fiskebäckskil, Sweden. This paper sketches changes in the distribution of well-being during the period from 1972 to 1991 against the background of West Germany's economic and demographic development, and compares the distribution of well-being in East Germany before and after reunification. We rely on equivalent income of persons as the main indicator to measure well-being, but we also look at the distribution of gross wage income of workers and employees. Estimates of the Federal Statistical Office referring to the mesolevel of average equivalent income of socio-economic groups as well as various distributional measures computed by us at the micro-level are used to gauge changes of the distribution. The computations are based on two sets of micro-data available to us, the official Income and Consumption Surveys (1973, 1978 and 1983), and the German Socio-economic Panel (1983 to 1990 for West Germany, 1990, 1991 for East Germany). At the meso-level we find substantial changes in the relative welfare positions of the ten socio-economic groups distinguished, but a nearly constant ranking of the groups during the whole period under review. At the micro-level our computations indicate slight increases in the inequality of gross earnings during both decades. The distribution of well-being as measured by equivalent income of persons seems also to have become slightly more unequal during the whole period but the changes are very small, and partly reversed during subperiods. A decomposition of overall inequality by occupational status of the heads of household using the Theil measure shows that more than 80 percent of overall inequality is due to within-group inequality with rising tendency. This result is mitigated a little when dis aggregating the heterogeneous group of not gainfully employed with regard to the main income source of the household.
Did earnings inequality in the Federal Republic of Germany increase from the 1960s to the 1980s?

This paper aims to provide a descriptive analysis of the changing patterns of labour market participation, non-participation and unemployment in Great Britain, Sweden and Germany. Since the mid 1970s, most European countries have experienced two parallel developments: on the one hand they have witnessed a huge growth in the proportion of women participating on the labour market. On the other however, they have experienced the return of mass unemployment and a growing insecurity of employment for those in work. In this paper, a typology of work histories is constructed using decade periods. Retrospective and panel data from Germany, Britain and Sweden are then used to compare the effects of different employment and welfare regimes on the proportions of respondents with different types of work histories and how these are combined with unemployment.
This paper fits within a broader research programme concerned with the processes that link labour market precarity and social exclusion. Labour market insecurity manifests itself most directly in the form of unemployment, and other elements in the programme seek to measure the impact of precarity, and unemployment in particular, on poverty and social exclusion in the eight countries covered. One of the principal concerns of the programme is however the extent to which institutional differences across countries with respect to the labour market and social protection are a significant factor mediating the relationship between labour market precarity and social exclusion. This paper focuses on the effectiveness of cash transfers, the central element of social protection systems, in alleviating the effects of unemployment on income poverty. The structures of social protection systems vary greatly across European Union member states, and in many cases have altered significantly in recent years in response to high unemployment (see Hauser et al, 1998). Using data from the mid-1980s and the mid-1990s for six member countries, the paper compares the effectiveness of different systems in lifting or keeping the unemployed out of poverty, and how this has been affected by the way systems have responded to the challenges produced by developments in the labour market in the past decade. The specific role of social insurance-based unemployment-linked transfers versus other cash transfers is also considered, to assess the extent to which social insurance has been able to cope with changes in the labour market over the period. The data come from a variety of national large-scale household surveys. The paper is structured as follows. Section 2 discusses the data and methods to be employed in measuring the impact of cash transfers on poverty risks for the unemployed. Section 3 looks at the overall risks of poverty for the unemployed before and after cash transfers, and how these changed between the mid-1980s and mid-1990s. Section 4 looks at the role of social insurance-based unemployment payments versus other cash transfers. Section 5 examines the extent to which the impact of transfers varies by gender and by duration of unemployment. Section 6 highlights the key patterns identified and what these tell us about the relationship between the type of welfare regime a country operates and effectiveness in alleviating poverty among the unemployed.
The structure of the compulsory pension system (CPS) in the Federal Republic of Germany has been changed fundamentally. The federal government has decided to introduce a private pension system on a voluntary basis. The payments to this voluntary system are to constitute a capital stock to supplement the payments of the compulsory pension system. Comprehensive fiscal subsidies will be introduced to support this change to the pension system. This paper discusses the special situation of families with children. The second section investigates the extent to which families with children were able to accumulate private wealth in the last ten years in Germany. In the third section the main features of the intended changes to the compulsory pension system are described, and an overview of the planned fiscal subsidies is provided. In the fourth and final section we attempt to evaluate the changes with particular attention to the situation of families.
This investigation of the wealth of private households as a possible indicator for the prosperity of a society indicated a strong increase in wealth for the Federal Republic of Germany since 1970. This applies both to the macro-economic results of the financial accounting of the Deutsche Bundesbank and to the micro-economic results of the Income and Consumption Surveys of the Federal Statistical Office. However, substantial differences become clear in the content expressed by these two different sets of data. While the financial accounting of the Deutsche Bundesbank shows an increase of net assets of around 808 per cent over 27 years (from 1.3 trillion DM in the year 1970 to 12.1 trillion DM in 1997), calculations on the basis of the Income and Consumption Surveys yield a corresponding value of only 280 per cent in a 25-year period, with a substantially lower overall magnitude in later investigations (from 2.2 trillion DM in 1973 to only 8.3 trillion DM in 1998). Investigation of the EVS data pointed out the great importance of property for the wealth situation of private households. However, not every household has property in the form of housing and real estate. In West Germany, ownership rates have increased substantially since 1962. However, since 1993 these rates have stagnated at about 50 per cent. The analysis of the distribution of wealth for West German households yielded a decline in the concentration of wealth in the period from 1973 to 1993, both in terms of the shares of total wealth held by individual quintiles of households, and as expressed by the Gini coefficients. However, this trend did not continue in the years between 1993 and 1998. For the year 1998 it can be determined that the lowest 40 per cent of households in West Germany had practically no wealth, while the highest quintile claimed over 60 per cent of total assets. For East Germany, strong tendencies are established toward adapting to the values in the West German Länder. This concerns first the absolute level of net assets, even though in 1998 these amounted to just 38 per cent of the analogous value in West German households, in terms of the average value per household. Similarly, the ownership rates of housing and real estate also rose dramatically after reunification. The inequality of the distribution of wealth in East Germany was reduced somewhat by this broader basis of real-estate ownership over the course of time, such that the Gini coefficient decreased slightly in the period from 1993 to 1998. However, it is also true for the new Länder in the Federal Republic that the lowest 40 per cent of households have practically no wealth, while the highest quintile of East German households claim over 70 per cent of total assets, even higher than its share in West Germany. Furthermore, the distribution of wealth is remarkably congruous in East and West Germany. Both the distribution of wealth as expressed by the quintile values and the results of the Gini coefficients yield similar results, whereby the trend in both regions is toward convergence. The similarity of these results must be regarded as nothing less than amazing, considering that the two regions followed different economic models for over forty years: the social free-market economy (Soziale Marktwirtschaft) in the Federal Republic of Germany, and the socialist planned economy (Sozialistische Planwirtschaft) in the German Democratic Republic.
Measuring confidence and uncertainty during the financial crisis : evidence from the CFS survey
(2010)
The CFS survey covers individual situations of banks and other companies of the financial sector during the financial crisis. This provides a rare possibility to analyze appraisals, expectations and forecast errors of the core sector of the recent turmoil. Following standard ways of aggregating individual survey data, we first present and introduce the CFS survey by comparing CFS indicators of confidence and predicted confidence to ifo and ZEW indicators. The major contribution is the analysis of several indicators of uncertainty. In addition to well established concepts, we introduce innovative measures based on the skewness of forecast errors and on the share of ‘no response’ replies. Results show that uncertainty indicators fit quite well with pattern of real and financial time series of the time period 2007 to 2010.

This paper provides theory as well as empirical results for pre-averaging estimators of the daily quadratic variation of asset prices. We derive jump robust inference for pre-averaging estimators, corresponding feasible central limit theorems and an explicit test on serial dependence in microstructure noise. Using transaction data of different stocks traded at the NYSE, we analyze the estimators’ sensitivity to the choice of the pre-averaging bandwidth and suggest an optimal interval length. Moreover, we investigate the dependence of pre-averaging based inference on the sampling scheme, the sampling frequency, microstructure noise properties as well as the occurrence of jumps. As a result of a detailed empirical study we provide guidance for optimal implementation of pre-averaging estimators and discuss potential pitfalls in practice.

Recent evaluations of the fiscal stimulus packages recently enacted in the United States and Europe such as Cogan, Cwik, Taylor and Wieland (2009) and Cwik and Wieland (2009) suggest that the GDP effects will be modest due to crowding-out of private consumption and investment. Corsetti, Meier and Mueller (2009a,b) argue that spending shocks are typically followed by consolidations with substantive spending cuts, which enhance the short-run stimulus effect. This note investigates the implications of this argument for the estimated impact of recent stimulus packages and the case for discretionary fiscal policy.
The global financial crisis has lead to a renewed interest in discretionary fiscal stimulus. Advocates of discretionary measures emphasize that government spending can stimulate additional private spending — the so-called Keynesian multiplier effect. Thus, we investigate whether the discretionary spending announced by Euro area governments for 2009 and 2010 is likely to boost euro area GDP by more than one for one. Because of modeling uncertainty, it is essential that such policy evaluations be robust to alternative modeling assumptions and different parameterizations. Therefore, we use five different empirical macroeconomic models with Keynesian features such as price and wage rigidities to evaluate the impact of fiscal stimulus. Four of them suggest that the planned increase in government spending will reduce private spending for consumption and investment purposes significantly. If announced government expenditures are implemented with delay the initial effect on euro area GDP, when stimulus is most needed, may even be negative. Traditional Keynesian multiplier effects only arise in a model that ignores the forward-looking behavioral response of consumers and firms. Using a multi-country model, we find that spillovers between euro area countries are negligible or even negative, because direct demand effects are offset by the indirect effect of euro appreciation.
The recent financial crisis has led to a major debate about fair-value accounting. Many critics have argued that fair-value accounting, often also called mark-to-market accounting, has significantly contributed to the financial crisis or, at least, exacerbated its severity. In this paper, we assess these arguments and examine the role of fair-value accounting in the financial crisis using descriptive data and empirical evidence. Based on our analysis, it is unlikely that fair-value accounting added to the severity of the current financial crisis in a major way. While there may have been downward spirals or asset-fire sales in certain markets, we find little evidence that these effects are the result of fair-value accounting. We also find little support for claims that fair-value accounting leads to excessive write-downs of banks’ assets. If anything, empirical evidence to date points in the opposite direction, that is, towards overvaluation of bank assets.
In this paper we investigate the comparative properties of empirically-estimated monetary models of the U.S. economy. We make use of a new data base of models designed for such investigations. We focus on three representative models: the Christiano, Eichenbaum, Evans (2005) model, the Smets and Wouters (2007) model, and the Taylor (1993a) model. Although the three models differ in terms of structure, estimation method, sample period, and data vintage, we find surprisingly similar economic impacts of unanticipated changes in the federal funds rate. However, the optimal monetary policy responses to other sources of economic fluctuations are widely different in the different models. We show that simple optimal policy rules that respond to the growth rate of output and smooth the interest rate are not robust. In contrast, policy rules with no interest rate smoothing and no response to the growth rate, as distinct from the level, of output are more robust. Robustness can be improved further by optimizing rules with respect to the average loss across the three models.
The goal of this research is to develop an understanding of what causes organizations and information systems to be “good” with regard to communication and coordination. This study (1) gives a theoretical explanation of how the processes of organizational adaptation work and (2) what is required for establishing and measuring the goodness of an organization with regard to communication and coordination. By leveraging concepts from cybernetics and philosophy of language, particularly the theoretical conceptualization of information systems as social systems and language communities, this research arrives at new insights. After discussing related work from systems theory, organization theory, cybernetics, and philosophy of language, a theoretical conceptualization of information systems as language communities is adopted. This provides the foundation for two exploratory field studies. Then a formal theory for explaining the adaptation of organizations via language and communication is presented. This includes measures for the goodness of organizations with regard to communication and coordination. Finally, propositions stemming from the theoretical model are tested using multiple case studies in six information system development projects in the financial services industry.

This dissertation analyzes tax policy, corporations, and capital market effects. First, the Savings Directive, which has left a loophole by providing grandfathering for some securities, is examined. It can be shown that investors are not willing to pay a premium for bonds that are exempt from the withholding rate, so it may be concluded that the supply of existing loopholes is large enough to allow tax evaders to continue evasion at no additional cost. Second, tax neutrality towards alternative financing instruments for corporate investment is a ubiquitous demand in the political debate. However, the magnitude of possible efficiency costs of a departure from tax neutrality is hardly discussed. Against this background, this dissertation discusses the theory of capital structure and provides back-ofthe-envelope calculations of the possible efficiency cost of a tax distortion of the debt-equity decision. Third, the ex-dividend-day effect in relation to the Gennan tax reform of 2000/2001 is discussed. The abolishment of the imputation system allows reinvestigating the size of the exdividend- day effect. I find no structural break in the size of the German ex-dividend-day effect and no evidence of an ex-dividend-day price drop that exceeds the dividend paid. Fourth, an account of the quantitative development of tax legislation in post-war Germany is presented. It can be shown that the legislative output did not increase over the decades and is not affected by a split majority in the upper and lower houses. Finally, it turns out that an increasing fraction of this legislation is passed in December.
This thesis is concerned with the derivation of new methods for the analysis of nonstationary, cross correlated panels. The suggested procedures are carefully quantified by means of Monte Carlo experiments. Typical applications of the developed methods consist in multi-country studies, with several countries observed over a couple of decades. The empirical applications implemented here are the testing for trends in the investment share in European GDPs and the examination of OECD interest rates. In the first chapter, a panel test for the presence of a linear time trend is proposed. The test is applicable in cross-correlated, heterogeneous panels and it can also be used when the integration order of innovations is unknown, by means of subsampling. In the next chapter a cointegration test having asymptotic standard normal distributiun and not requiring exogeneity assumptions is derived. In panels exhibiting cross-correlation or cointegration, individual test statistics are asymptotically independent, which leads to a panel test statistic robust to dependence across units. The third chapter examines in an econometric context the simple idea of combining p-values from a series of statistical tests and improves its applicability in the presence of cross-correlation. The last chapter applies recent panel techniques to OECD long-term interest rates and differentials thereof, finding only rather week evidence in favor of stationarity when allowing for cross-correlation.
The paper explores factors that influence the design of financing contracts between venture capital investors and European venture capital funds. 122 Private Placement Memoranda and 46 Partnership Agreements are investigated in respect to the use of covenant restrictions and compensation schemes. The analysis focuses on the impact of two key factors: the reputation of VC-funds and changes in the overall demand for venture capital services. We find that established funds are more severely restricted by contractual covenants. This contradicts the conventional wisdom which assumes that established market participants care more about their reputation, have less incentive to behave opportunistically and therefore need less covenant restrictions. We also find that managers of established funds are more often obliged to invest own capital alongside with investors money. We interpret this as evidence that established funds have actually less reason to care about their reputation as compared to young funds. One reason for this surprising result could be that managers of established VC funds are older and closer to retirement and therefore put less weight on the effects of their actions on future business opportunities. We also explore the effects of venture capital supply on contract design. Gompers and Lerner (1996) show that VC-funds in the US are able to reduce the number of restrictive covenants in years with high supply of venture capital and interpret this as a result of increased bargaining power by VC-funds. We do not find similar evidence for Europe. Instead, we find that VC-funds receive less base compensation and higher performance related compensation in years with strong capital inflows into the VC industry. This may be interpreted as a signal of overconfidence: Strong investor demand seems to coincide with overoptimistic expectations by fund managers which make them willing to accept higher powered incentive schemes.
