This paper investigates the risk channel of monetary policy on the asset side of banks’ balance sheets. We use a factoraugmented vector autoregression (FAVAR) model to show that aggregate lending standards of U.S. banks, such as their collateral requirements for firms, are significantly loosened in response to an unexpected decrease in the Federal Funds rate. Based on this evidence, we reformulate the costly state verification (CSV) contract to allow for an active financial intermediary, embed it in a New Keynesian dynamic stochastic general equilibrium (DSGE) model, and show that – consistent with our empirical findings – an expansionary monetary policy shock implies a temporary increase in bank lending relative to borrower collateral. In the model, this is accompanied by a higher default rate of borrowers.
In this lecture, the context and conditions of becoming a teacher from the time of being selected into the programme, through the process of training and being retained to teach are discussed within the framework of Teacher Education in Nigeria. First, the concepts and the history of teacher education are examined. Then, some critical issues as well as my personal research efforts on teacher education are discussed. Finally, recommendations for meeting the challenges of Teacher Education in Nigeria are made.
We find that on average consumers chose the contract that ex post minimized their net costs. A substantial fraction of consumers (about 40%) still chose the ex post sub-optimal contract, with some incurring hundreds of dollars of avoidable interest costs. Nonetheless, the probability of choosing the sub-optimal contract declines with the dollar magnitude of the potential error, and consumers with larger errors were more likely to subsequently switch to the optimal contract. Thus most of the errors appear not to have been very costly, with the exception that a small minority of consumers persists in holding substantially sub-optimal contracts without switching.

The reaction of consumer spending and debt to tax rebates – evidence from consumer credit data
(2008)
We use a new panel dataset of credit card accounts to analyze how consumer responded to the 2001 Federal income tax rebates. We estimate the monthly response of credit card payments, spending, and debt, exploiting the unique, randomized timing of the rebate disbursement. We find that, on average, consumers initially saved some of the rebate, by increasing their credit card payments and thereby paying down debt. But soon afterwards their spending increased, counter to the canonical Permanent-Income model. Spending rose most for consumers who were initially most likely to be liquidity constrained, whereas debt declined most (so saving rose most) for unconstrained consumers. More generally, the results suggest that there can be important dynamics in consumers’ response to “lumpy” increases in income like tax rebates, working in part through balance sheet (liquidity) mechanisms.
Visibility and digital accessibility of the School of Salamanca in a linked open-data environment
(2019)
This paper raises the bibliographic and technological approach to increasing visibility and accessibility of the work of the School of Salamanca in the current technological state of the web. The objective is to avoid the cultural effect of not acting in this field, for which authors draw an analogy with Plantin's privilege in 16th-Century Spanish printing. The Virtual Library of the School of Salamanca is described as a Linked Open-Data resource about the authors of this school and their digitized works, in which the relationships between authors and concepts are crucial. For this purpose, different properties of the DBpedia ontology are used, and the descriptions of the authors are systematically linked to other Linked Open-Data resources. All descriptions (authors, works and concepts) are offered in Europeana Data Model and MARC 21. Also discussed are the advantages of Wikipedia and Wikidata in increasing visibility.
A summary of this text was presented at the international conference organized by the Max Planck Institute for the History of European Law: "The School of Salamanca: A Case of Global Knowledge Production?", held in Buenos Aires from 24th to 26th October 2018.
Education is the major issue in this lecture, it is followed by national development, which is its target, and Educational Planning which is the chief tool for getting to the target. Education had developed in Nigeria from 1842 to 1959 without the operators consciously directing it to national development but because of the new needs, new aspiration and new attitudes in an independent Nigeria; education was then directed towards national development. In the 60s all the efforts made to prepare the kind of education to serve the interest of National development failed because there was no effective method to do this. But in the 70s educational planning was discovered as an effective technique for preparing or planning an appropriate education for national development in terms of policies, programmes, enrolment, skill acquisition and manpower development.
Modeling short-term interest rates as following regime-switching processes has become increasingly popular. Theoretically, regime-switching models are able to capture rational expectations of infrequently occurring discrete events. Technically, they allow for potential time-varying stationarity. After discussing both aspects with reference to the recent literature, this paper provides estimations of various univariate regime-switching specifications for the German three-month money market rate and bivariate specifications additionally including the term spread. However, the main contribution is a multi-step out-of-sample forecasting competition. It turns out that forecasts are improved substantially when allowing for state-dependence. Particularly, the informational content of the term spread for future short rate changes can be exploited optimally within a multivariate regime-switching framework.
This study uses Markov-switching models to evaluate the informational content of the term structure as a predictor of recessions in eight OECD countries. The empirical results suggest that for all countries the term spread is sensibly modelled as a two-state regime-switching process. Moreover, our simple univariate model turns out to be a filter that transforms accurately term spread changes into turning point predictions. The term structure is confirmed to be a reliable recession indicator. However, the results of probit estimations show that the markov-switching filter does not significantly improve the forecasting ability of the spread.
In this study a regime switching approach is applied to estimate the chartist and fundamentalist (c&f) exchange rate model originally proposed by Frankel and Froot (1986). The c&f model is tested against alternative regime switching specifications applying likelihood ratio tests. Nested atheoretical models like the popular segmented trends model suggested by Engel and Hamilton (1990) are rejected in favour of the multi agent model. Moreover, the c&f regime switching model seems to describe the data much better than a competing regime switching GARCH(1,1) model. Finally, our findings turned out to be relatively robust when estimating the model in subsamples. The empirical results suggest that the model is able to explain daily DM/Dollar forward exchange rate dynamics from 1982 to 1998.
A common prediction of macroeconomic models of credit market frictions is that the tightness of financial constraints is countercyclical. As a result, theory implies a negative collateralizability premium; that is, capital that can be used as collateral to relax financial constraints provides insurance against aggregate shocks and commands a lower risk compensation compared with non-collateralizable assets. We show that a longshort portfolio constructed using a novel measure of asset collateralizability generates an average excess return of around 8% per year. We develop a general equilibrium model with heterogeneous firms and financial constraints to quantitatively account for the collateralizability premium.
