The Impact of Risk-Based Premiums on FDIC-Insured Institutions

This paper examines the effect of a series of announcements leading to the approval of risk-based deposit insurance premiums on returns to stockholders of commercial banks. Utilizing risk-weighted capital ratios and measures of overall risk, we group banks according to one of the nine-tier insurance categories subsequently defined by the FDIC. During the period in which the new insurance system was considered and approved, we found that stockholders of well-capitalized, healthy banks experienced wealth changes significantly different from those experienced by less than well-capitalized, less than healthy banks. Although many argued the premium range in the initial insurance schedule was insufficient, the results show that this initial risk-basing marked an important change in the relative burdens imposed by FDIC insurance.     

Can International Factor Mobility Reduce Wage Inequality in a Dual Economy?*

This paper analyzes the consequences of international factor movements on the skilled–unskilled wage inequality in a dual‐economy set‐up that includes unemployment and three intersectorally mobile factors of production—unskilled labor, skilled labor, and capital. Thus far, theoretical literature on this subject has adopted the full‐employment framework and hence ignored the problem of unemployment. The analysis in this paper reveals that the results crucially depend on the difference in the intersectoral factor intensities between skilled labor and capital. In particular, it demonstrates the existence of a possibility of deterioration in wage inequality following foreign unskilled‐labor inflow.     

The economics of conflicts of interest in financial institutions

A conflict of interest exists when a party to a transaction can gain by taking actions that are detrimental to its counterparty. This paper examines the growing empirical literature on the economics of conflicts of interest in financial institutions. Economic analysis shows that, although conflicts of interest are omnipresent when contracting is costly and parties are imperfectly informed, there are important factors that mitigate their impact and, strikingly, it is possible for customers of financial institutions to benefit from the existence of such conflicts. The empirical literature reaches conclusions that differ across types of conflicts of interest but are overall more ambivalent and certainly more benign than the conclusions drawn by journalists and politicians from mostly anecdotal evidence.     

International Trade and Growth: An Overview Using the New Growth Theory

An overview of the new growth theory is provided from both an analytical and empirical perspective. Following a historical outline and a brief analytical sketch of the R&D-based models, the results from fitting two structural models to data are presented. Results show the relative impacts on growth from trade and R&D-based policies including technological spillovers from trade. The mechanism of intersectoral adjustments to the long-run growth path is also discussed. Insights provided by the theory are related to agriculture from the view of agriculture in the context of the broader economy within which it must compete for resources, and in terms of growth in agricultural factor productivity as evidenced by the recent growth in genetic engineering.     

Information acquisition,foreign bank entry,and credit allocation

This paper presents a theoretical framework to understand the impact of foreign bank entry on the access to and the price of credit for different types of firms. A major point of departure from the previous literature is that incumbents’ information about firms is endogenous in the model; previous screenings and lending relations of incumbents determine which type(s) of firms they can identify. I show that incumbents’ information is negatively correlated with the quality of borrowers. Moreover, although a priori entrants have a comparative advantage in lending to transparent firms, previous lending relations of incumbents might reverse this relation. In particular, given that transparent firms are the only type screened before the entry and therefore they are the only type distinguishable by incumbents, entrants might have a comparative advantage in lending to opaque firms. The analysis provides new insights into the inconclusive evidence of the literature regarding entrants’ credit allocation.

An elementary proposition on technical progress and non-traded goods

We explore the effect of technical progress on the endogenously determined range of non-traded goods by using a Ricardian model with continuum of goods. By defining technical progress on the basis of proportional changes in the relative productivity across sectors, we show that the range of non-traded goods decreases if technical progress is unbiased or if it is biased toward the goods that a country has more comparative advantage.
