Trade and the distribution of human capital

We develop a two-country, two-sector model of trade where the only difference between the two countries is their distribution of human capital endowments. We show that even if the two countries have identical aggregate human capital endowments the pattern of trade depends on the properties of the two human capital distributions. We also show that the two distributions of endowments also completely determine the effects of trade on income inequality. We also look at a simple majority voting model. It turns out autarky and free trade with and without compensation may be the voting outcome.     

Long-Term Financial Contracts and Technological Choice

The paper establishes a theoretical link between financial innovation and economic development. In an economic environment where product development takes place, it is shown that the gains from long-term financial contracting go beyond the minimization of costs associated with frictions in the capital markets. They can also result in the adoption of more efficient technologies by the production sector. Furthermore, the model suggests that financial innovation is also a byproduct of economic development, providing a possible explanation for the lack of long-term financial markets in less-developed economies.     

On the Trade-off Between Work-related Training and Labor Mobility: The Role of Firing and Exit Costs

Within an incomplete-contract framework, we examine the consequences of contract renegotiation for contract design/enforcement and training market efficiency. Specifically, we show how the imposition of either firing costs or exit costs can bind together employers and employees in longer-lasting employment relationships that allow both agents to amortize their training investments. Nevertheless, the model implies that, although firing and exit costs provide institutional solutions to the training under-investment problem, this is achieved at the expense of allocative efficiency (efficient separations). Empirical evidence supports the existence of such a trade-off.revised version received July 23, 2003     

Is R & D Financially Constrained? Theory and Evidence from Irish Manufacturing

We re-examine the effects of liquidity constraints on R & D investment. Inour theoretical section we extend the neoclassical framework of investmentin physical capital by introducing R & D and liquidity constraints. Weanalyse this issue empirically using firm-level data for R & D activemanufacturing firms in the Republic of Ireland. Our results provide evidencethat suggests that R & D investment is financially constrained. This is inline with previous studies of U.S. firms.     

International aspects of public infrastructure investment

Abstract.  Modelling infrastructure as an international public good in a two‐country model of trade where each country's social planner behaves strategically, we show that, in general, the equilibrium levels of infrastructure are not optimal from a global perspective. Utilizing an appropriate econometric framework and data from 16 European countries over the period 1987–95, we find evidence that is consistent with the predictions of our model. JEL Classification: F10, F42, H42
Aspects internationaux de l'investissement public dans les infrastructures.  Les auteurs présentent un modèle de commerce international entre deux pays dans lequel (1) les planificateurs des deux pays ont un comportement stratégique et (2) les infrastructures sont un bien public international. Ils montrent que, en général, les niveaux d'équilibre des investissements en infrastructure ne sont pas optimaux d'un point de vue global. A l'aide d'un cadre économétrique approprié, et de données pour 16 pays européens entre 1987 et 1995, ils valident les prédictions de leur modèle.     

Internal vs External Financing of R&D

The empirical evidence suggests that while small firms in United States, United Kingdom and Canada rely on internal funds for financing R&D, similar firms in Japan, Germany and France have access to bank loans. In this paper, we analyze the financial decisions of small firms willing to invest in R&D. We find that their high ratio of intangible assets, along with the high risk nature of their investments, can explain their inability to raise debt in external capital markets. We also show that financing R&D with bank loans might be feasible, especially, if banks are willing to monitor the investment activities of their clients.     

Foreign currency borrowing,exports and firm performance: evidence from a currency crisis

This paper develops a simple signaling model of foreign currency borrowing that yields predictions about firm survival and performance during a currency crisis. Using a large panel of firm level data for South Korea we offer empirical support for many of the predictions of our model, while others support predictions that cannot be tested using our data. Our paper demonstrates that although firms that borrow in foreign currency are more likely to exit after the currency collapses, those that continue to produce perform better. Among them, the best performers are exporters whose foreign sales are more competitively priced under a devalued currency.     

Infrastructure, specialization, and economic growth

We introduce infrastructure as a cost-reducing technology in Romer's (1987) model of endogenous growth. We show that infrastructure can promote specialization and long-run growth, even though its effect on the latter is non-monotonic, reflecting its resource costs. We provide evidence using data from the U.S. Census of Manufactures that suggests that the degree of specialization is positively correlated with core infrastructure, as predicted by the model. We also provide evidence from cross-country regressions, using physical measures of infrastructure provision, that shows a robust non-monotonic relationship between infrastructure and growth. JEL Classification: 041,050
Les auteurs introduisent l'infrastructure en tant que technologie réduisant les coûts dans un modèle de croissance endogène à la Romer (1987). On montre que l'infrastructure peut promouvoir la spécialisation et la croissance en longue péride, même si ses effets sur la croissance ne sont pas monotones et reflètent ses coûts en ressource. On montre, en utilisant les données du recensement des manufactures des Etats Unis, que le degré de spécialisation est relié positivement à l'infrastructure de base, comme le suggère le modèle. On montre aussi à l'aide de régressions transversales, utilisant des mesures physiques de l'infrastructure, qu'il existe une relation non monotone mais robuste entre infrastructure et croissance.     

Corporate trade credit and inventories: New evidence of a trade-off from accounts payable and receivable

Trade credit is an important source of finance for firms and has been well researched, but the focus has been on financial trade-offs. In this paper, we consider the trade-offs with inventories and develop a simple model that recognizes the incentives a firm faces to offer and receive trade credit. Our model identifies the response of accounts payable and accounts receivable to changes in the cost of inventories, profitability, risk and liquidity, and importantly, this influence operates through a production channel. Our results support the model and complement many existing studies focused on explaining the financial terms of trade credit.
