Trade Costs,Trade Balances and Current Accounts: An Application of Gravity to Multilateral Trade

In this paper we test the well-known hypothesis of Obstfeld and Rogoff (NBER Macroeconomics Annual 7777:339–390, 2000) that trade costs are the key to explaining the so-called Feldstein–Horioka puzzle. Our approach has a number of novel features. First, we focus on the interrelationship between trade costs, the trade account and the Feldstein–Horioka puzzle. Second, we use the gravity model to estimate the effect of trade costs on bilateral trade and, third, we show how bilateral trade can be used to draw inferences about desired trade balances and desired intertemporal trade. Our econometric results provide strong support for the Obstfeld and Rogoff hypothesis and we are also able to reconcile our results with the so-called home bias puzzle.

Financial Turmoil, Failed Bank Acquisitions, and Bank Business Lending Behavior

This paper utilizes bank Call Report and FDIC receivership data from 1987 to 1991 to examine the impact of a failed bank acquisition on the growth rate of commercial and industrial (C&I) lending at the acquiring institutions. Using a two-stage least squares model with fixed effects, we find that banks acquiring a failed bank's assets experience a significant decline in both the growth rate of C&I lending and their capital asset ratios in the period of the acquisition. The results support anecdotal evidence that failed-bank borrowers may experience difficulties in accessing credit once their bank fails and underscores the importance of bank-borrower relationships in C&I lending. Finally, the paper provides an alternative explanation for banks' stagnant or declining business lending activity during this period of financial turmoil.     

Connectivity in the Commercial Internet

We study the 'backbone market' in the Internet. After discussing the structure of the Internet, we use an extension of the Katz-Shapiro network model to analyze the strategies that would be used by dominant backbone. We show that a larger backbone prefers a lower quality interconnection than the smaller one. We then analyze a 'targeted degradation' strategy where the larger backbone lowers the quality of interconnection to its smaller rivals in turn. Finally, we show that the qualitative results are robust to the possibility of 'multihoming' by clients.     

PRIMITIVE ACCUMULATION,GROWTH AND THE GENESIS OF SOCIAL CLASSES

The aim of this paper is to show that inequalities of wealth can be necessary conditions to explain the apparition and rise of a capitalistic system. We try to highlight Marx's insights on primitive accumulation. Our dynamic framework is consistent with Roemer's idea of endogenous class stratification. We extend this calculation by incorporating some features of the Pasinetti–Samuelson–Modigliani model, and provide an example of possible microfoundations.     

International Trade Agreements and International Migration

Despite large potential economic gains, bilateral and multilateral negotiations focusing on liberalisation of migration have not shared the high profile of international trade negotiations and agreements. Migration and trade have been traditionally viewed rather separately and the relevance of the many, and complex, interdependencies has been given remarkably little attention in the literature to date. In this article, we focus on the two‐way interaction between international migration and agreements designed to enhance cross‐border trade and investment. Liberalisation of international trade in services and in the movement of people potentially offers much greater economic gains than liberalisation of remaining barriers to goods trade. However, progress within multilateral frameworks is fraught with difficulty. The World Trade Organization’s General Agreement on Trade in Services (GATS) has yielded little real progress so far and negotiations within more flexible unilateral and bilateral frameworks are likely to be more successful in liberalising the movement of labour. We discuss a range of specific examples, focusing particularly on the interesting case of New Zealand. We find that trade agreements are increasingly including agreements on migration, though typically favouring temporary migration and involving numerically modest quotas. We conclude that migration regulatory frameworks are likely to be further and more strongly linked to trade and investment agreements in the future, particularly given changing economic and demographic forces. The primary focus of migration policies may nonetheless remain different from that of trade policies. While further migration liberalisation is likely to be through bilateral and regional agreements, it will be important to try to lock in the gains of such agreements, while simultaneously working to consolidating these in a way that will help to facilitate future multilateral agreement.     

A simple proof of Blackwell's “comparison of experiments” theorem

This note presents a simple proof of Blackwell's well-known theorem on the equivalence of two orderings of experiments, one based on the statistical concept of sufficiency, and the other on the economic concept of the value to the decision makers.     

Convergence - the Maastricht approach to economic and monetary union (EMU) in Europe

This article reviews the concept of convergence in the Maastricht Treaty and notes that, while in certain areas the convergence objectives are quite ambitious, in other areas the objectives for the transition period are surprisingly limited. By end-1992, much progress had already been achieved on convergence in a majority of EC countries (and countries applying for membership). Thus, despite the wave of pessimism that followed the recent exchange market crisis, it is still quite possible that a majority of EC members could qualify for monetary union by 1997. However, this would require further significant adjustment in many cases in the fiscal area. Based on the Multimod Model used at the Fund, the deflationary effect of this fiscal consolidation would be small and short lived.     

A note on control costs and logit rules for strategic games

We consider best response dynamics with endogenous noise based on a finite game in strategic form. A player can reduce the noise level by expending an extra effort and incurring some disutility or control costs. We specify control costs that result in logit adjustment rules. The stochastically stable states of the dynamic process are partial Nash configurations, that is, states where at least one player plays a best response against the others. If the game has a potential, then the stochastically stable states coincide with the Nash equilibria on which the potential is maximized.

Evidence on the impact of R&D and ICT investments on innovation and productivity in Italian firms

Both research and development (R&D) and information and communication technology (ICT) investment have been identified as sources of relative innovation underperformance in Europe vis-à-vis the USA. In this article, we investigate the R&D and ICT investment at the firm level in an effort to assess their relative importance and to what extent they are complements or substitutes. We use data on a large unbalanced panel data sample of Italian manufacturing firms constructed from four consecutive waves of a survey of manufacturing firms, to estimate a version of the CDM model of R&D, innovation, and productivity [Crépon–Duguet–Mairesse 1998. Research, innovation and productivity: An econometric analysis at the firm level. Economics of Innovation and New Technology 7, no. 2: 115–58] that has been modified to include ICT investment and R&D as the two main inputs into innovation and productivity. We find that R&D and ICT are both strongly associated with innovation and productivity, with R&D being more important for innovation, and ICT investment being more important for productivity. For the median firm, rates of return to both investments are so high that they suggest considerably underinvestment in both these activities. We explore the possible complementarity between R&D and ICT in innovation and production, but find none, although we do find complementarity between R&D and worker skill in innovation.
