In the aftermath of the global financial crisis, the state of macroeconomic modeling and the use of macroeconomic models in policy analysis has come under heavy criticism. Macroeconomists in academia and policy institutions have been blamed for relying too much on a particular class of macroeconomic models. This paper proposes a comparative approach to macroeconomic policy analysis that is open to competing modeling paradigms. Macroeconomic model comparison projects have helped produce some very influential insights such as the Taylor rule. However, they have been infrequent and costly, because they require the input of many teams of researchers and multiple meetings to obtain a limited set of comparative findings. This paper provides a new approach that enables individual researchers to conduct model comparisons easily, frequently, at low cost and on a large scale. Using this approach a model archive is built that includes many well-known empirically estimated models that may be used for quantitative analysis of monetary and fiscal stabilization policies. A computational platform is created that allows straightforward comparisons of models’ implications. Its application is illustrated by comparing different monetary and fiscal policies across selected models. Researchers can easily include new models in the data base and compare the effects of novel extensions to established benchmarks thereby fostering a comparative instead of insular approach to model development.
How do changes in market structure affect the US business cycle? We estimate a monetary DSGE model with endogenous
rm/product entry and a translog expenditure function by Bayesian methods. The dynamics of net business formation allow us to identify the 'competition effect', by which desired price markups and inflation decrease when entry rises. We
find that a 1 percent increase in the number of competitors lowers desired markups by 0.18 percent. Most of the cyclical variability in inflation is driven by markup fluctuations due to sticky prices or exogenous shocks rather than endogenous changes in desired markups.
This paper characterises optimal monetary policy in an economy with endogenous
firm entry, a cash-in-advance constraint and preset wages. Firms must make pro
fits to cover entry costs; thus the markup on goods prices is efficient. However, because leisure is not priced at a markup, the consumption-leisure tradeoff is distorted. Consequently, the real wage, hours and production are suboptimally low. Due to the labour requirement in entry, insufficient labour supply also implies that entry is too low. The paper shows that in the absence of
fiscal instruments such as labour income subsidies, the optimal monetary policy under sticky wages achieves higher welfare than under flexible wages. The policy maker uses the money supply instrument to raise the real wage - the cost of leisure - above its flexible-wage level, in response to expansionary shocks to productivity and entry costs. This raises labour supply, expanding production and
rm entry.

We investigate the decisions of listed firms to go private once again. We start by revealing that while a significant number of firms which go public is VC-backed, an overproportional share of these VC-backed firms go private later on (they stay on the exchange for an average of 8.5 years). We interpret this very robust pattern such that IPOs of VC-backed firms are to a large extent a temporary rather than a permanent feature of the corporate governance of these firms. We investigate various potential hypotheses why VCs actually seem to be able to bring marginal firms to the exchange by relating the going-private decisions to various characteristics of the IPO market as well as to VC characteristics. We find strong support for the certification ability of VCs: more experienced and reputable VCs are more able to bring marginal firms to public exchanges via an IPOs. These marginal firms backed-by more reputable and experienced VCs are more likely to go private later on. Hence, our analysis suggests that IPOs backed by experienced VCs are most likely to be a temporary rather than the final stage in the life of the portfolio firm. We find no support that reputable VCs underprice their IPO-exits more implying that they have no need to leave more money on the table to take the marginal firms public.
In the last two decades Philippine languages, and of these especially Tagalog, have acquired a prominent place in linguistic theory. A central role in this discussion was played by two papers written by Schachter (1976 and 1977), who was inspired by Keenan's artcle on the subject from 1976. The most recent contributions on this topic have been from de Wolff (1988) and Shibatani (1988), both of which were published in a collection of essays, edited by Shibatani, with the title Passive and Voice. These works, and several works in-between, deal with the focus system specific to Philippine languages. The main discussion centers around the fact that Philippine languages contain a basic set of 5 to 7 affix focus forms. Their exact number varies not only in the secondary literature, but in the primary sources, i.e. Tagalog grammars, as well, where considerable differences in the number of affix focus forms can be found. All of these works, however, do agree on one point: the Philippine focus system basica1ly consists of agent, patient (=goal or object), benefactive, locative, and instrumental affix forms. Schachter/Otanes (1972) list a number of further forms, and in Drossard (1983 and 1984) we tried to show (in an attempt similar to those of Sapir 1917 and Klimov 1977) that the main criterion for a systematization of the Philippine focus system consists in the difference between the active and stative domains, an attempt which in our opinion was largely misunderstood (cf. the brief remarks in Shibatani (1988) and de Wolff (1988). The present paper is thus, on the one hand, an attempt to repeat and clarify our earlier position, and on the other, a further step towards such a systematization. A first step in this direction was an article on resultativity in Tagalog from 1991. In the present paper this approach will be extended to reciprocity. In the process we will show that it is valid to make a distinction between an active (=controlled action) vs. a stative (=limited controlled action) domain. First, however, we will take a brief look at what makes up the active and stative voice systems.
This paper is concerned with developing Joan Bybee's proposals regarding the nature of grammatical meaning and synthesizing them with Paul Hopper's concept of grammar as emergent. The basic question is this: How much of grammar may be modeled in terms of grammaticalization? In contradistinction to Heine, Claudi & Hünnemeyer (1991), who propose a fairly broad and unconstrained framework for grammaticalization, we try to present a fairly specific and constrained theory of grammaticalization in order to get a more precise idea of the potential and the problems of this approach. Thus, while Heine et al. (1991:25) expand – without discussion – the traditional notion of grammaticalization to the clause level, and even include non-segmental structure (such as word order), we will here adhere to a strictly 'element-bound' view of grammaticalization: where no grammaticalized element exists, there is no grammaticalization. Despite this fairly restricted concept of grammaticalization, we will attempt to corroborate the claim that essential aspects of grammar may be understood and modeled in terms of grammaticalization. The approach is essentially theoretical (practical applications will, hopefully, follow soon) and many issues are just mentioned and not discussed in detail. The paper presupposes a familiarity with the basic facts of grammaticalization and it does not present any new facts.
Grammatical relations – in particular the relation 'subject of' – and voice are of central concern to any theory of universal grammar. With respect to these phenomena the analysis of Tagalog (and the Philippine languages in general) has turned out to be particularly difficult and continues to be a matter of debate. What traditionally has been called passive voice in these languages […] appears to be so different from voice phenomena in the more familiar Indo-European languages that the term 'focus' was introduced in the late 1950s to underscore its 'exceptional' nature [...]. Furthermore, […] an inflationary use has been made of the term 'ergative' in the last decade; it can thus no longer be assumed that it has an unequivocal and specific meaning in typologizing languages, apart from the technical definition it might be given within a particular framework. But if the Philippine 'focus' constructions are neither passive nor ergative, how else can they be analysed? [...] In this paper a ease will be made for the claim that 'focus' marking should be analysed in terms of orientation, a concept used […] for capturing the difference between English (and, more generally, Indo-European) orientated nominalisations such as 'employ-er' or 'employ-ee', and unorientated nominalisations such as 'employ-ing'. This approach implies that 'focus' marking is derivational rather than inflectional as often presumed in the literature. This is to say that what is typologically conspicuous in Tagalog is not the 'focus' phenomenon per se, since this is very similar to orientated nominalisations in many other languages, but rather the very prominent use of orientated formations (i.e., derivational morphology) in basic clause structure.
The most macabre of the numerous anthropomorphic metaphors linguists provide for their subject matter is that of language death. The extinction of a language is in fact a distressing matter, because the cultural tradition connected to it and the sociocultural or even ethnic independence of the group that speaks it very often perish together with it. Yet it is a very common phenomenon. [...] It would seem strange that such a frequent and well-known phenomenon has not been studied much earlier; nevertheless it is a fact that the investigation of language death is a new and developing field, which emerged as something like an independent subdiscipline of linguistics towards the end of the seventies. This comparatively embryonic stage of the field should be kept in mind throughout the following discussion.
