An empirical investigation of the effect of borrowing constraints on Spanish consumption

Abstract. This work analyses the relevance of borrowing constraints on the intertemporal behaviour of Spanish non-durable consumption. We estimate Euler equations with cohort data extracted from the “Encuesta Continua de Presupuestos Familiares” (ECPF) for the period 1985–1993. The results are robust to the use of different estimators to eliminate fixed individual effects, to different specifications of the model, to the effect of uncertainty and to the presence of habits in consumption. Our results allow us to conclude that non-durable consumption of a considerable fraction of the Spanish population is affected by borrowing constraints. At the same time, and in accordance with similar results for other countries, we confirm that borrowing constraints are especially important for the young.

Firm-provided training and temporary contracts

This paper analyses the relationship between workers type of contract and the probability of receiving firm-provided training. In particular, we raise the following question: do workers with temporary contracts face the same probability of receiving training as workers with permanent contracts, once we account for the fact that both types of workers have different probabilities of being employed in a firm providing training? The results from our empirical analysis using data from the Spanish labour market suggest that workers with temporary contracts not only are less likely to be employed in training firms but, once they are in those firms, they also have a lower probability of being chosen to participate in firm-provided training activities.JEL Classification: J23, M53Authors gratefully acknowledge financial support from Universidad de Alcalá under research project La relación entre temporalidad y formación en la empresa: un análisis comparativo entre los países de la Unión Europea (award no.

Human capital,innovation and productivity in Colombian enterprises: a structural approach using instrumental variables

ABSTRACT

In this paper we explore the R&D–innovation–productivity linkage for the Colombian manufacturing industry, paying special attention to the role of human capital. Using data from two firm-level surveys, the Survey of Development and Technological Innovation (EDIT) and the Annual Manufacturing Survey (EAM), we extend the model of Crépon, Duguet, and Mairesse [1998. ‘Research, Innovation and Productivity: An Econometric Analysis at the Firm Level.’ Economics of Innovation and New Technology 7 (2): 115–158] (hereafter CDM) by including human capital at the investment decision stage. We implement an instrumental variable methodology to correct the potential endogeneity that may arise with the inclusion of human capital. Our results suggest that human capital has a causal effect on research and development (R&D) investment decisions, the innovation behavior of the firm, and increases the labor productivity of the firm. The conclusions highlight the relevance of human capital in the surrounding literature which stands in contrast to prior work that has not included this variable.     

Optimal money growth in a limited participation model with heterogeneous agents

This paper studies optimal money growth in a cash-in-advance production economy with heterogeneity in patience levels and know-how. We show that the rate of deflation suggested by the Friedman rule is limited by the subjective discount rate of the most patient agent in the economy. The output distortion due to cash-in-advance constraints on firms can completely be eliminated by means of the Friedman rule if and only if firms are run by the most patient agents.Received: 16 August 2003, Accepted: 22 March 2005, JEL Classification: D52, D90, E21, E41, E52Parts of this paper were completed while the first and second authors were visiting the University of York and Princeton University respectively.

Discrete representations of a continuum economy

We consider an atomless economy in which the continuum of agents is represented by a real interval. By dividing the interval and associating to every agent in each subinterval the same initial endowments and preferences, we define sequences of discrete economies as approximations to the initial continuum economy. We obtain convergence results for the core (or, alternatively, for the set of Walrasian allocations) of the continuum economy in terms of the cores of the approximating discrete economies. Finally, we state some counterexamples which provide a boundary for more general results in this framework. Received: 29 December 2000 / Accepted: 28 April 2002 C. Hervés and E.

Derivative prices from interest rate models: results for Canada, Hong Kong, and United States

In this paper, we compute implied bond and contingent claim prices from the CKLS, Vasicek, CIR, and BS interest rate models using historical estimates for Canada, Hong Kong, and the United States. We find that default-free bond prices and contingent claim prices are sensitive to the assumed model used for these currencies, and that for Canada the CIR is the best, for Hong Kong the Vasicek and CIR models, and for the US the BS model.     

Federal Home Loan Bank Lending to Community Banks: Are Targeted Subsidies Desirable?

The Gramm-Leach-Bliley Act of 1999 amended the lending authority of the Federal Home Loan Banks to include advances secured by small enterprise loans of community financial institutions. Three reasons for the extension of this selective credit subsidy to community banks and thrifts are examined, including the possible need to: subsidize community depository institutions, stabilize the Federal Home Loan Banks, and address a market failure in rural markets for small enterprise loans. We empirically investigate whether funding constraints impact the small-business lending decision by rural community banks. We estimate static and dynamic models of small-business lending by community banks. The data reject the hypothesis that access to increased funds will increase the amount of small-business loans made by community banks.     

Conceptualizing digital and physical connectivity: The position of European cities in Internet backbone and air traffic flows

‘Digital’ telecommunication flows and ‘physical’ corporeal flows provide researchers with comprehensive indicators of the economic interactions between cities. However, previous research drawing on telecommunication-based measures of inter-urban connectivity has been hampered by inadequate conceptualizations and data. This paper draws on this observation to devise a new approach for measuring inter-urban connectivity based on a city’s insertion in Internet backbone networks. The straightforward example of air transport flows is thereby used to outline this approach. To investigate telecommunication and air passenger flows, use is made of European statistics on Internet eXchange Points and the MIDT airline database respectively. The approach is illustrated through a systematic comparison of the position of European cities in both types of networks. It is found that European cities assume largely similar hierarchical levels in terms of digital and physical information flows, albeit that the digital connectivity of centrally located European cities is often somewhat higher than that of peripheral cities with a similar levels of physical connectivity.
