Eastern European Economic Integration and Foreign Direct Investment

Economic transition in Eastern Europe should generate market growth. In addition, current discussions on economic integration and the development of a free-trade area in Eastern Europe will improve market accessibility. These two forces will significantly affect the strategies by which external firms will choose to supply markets in Eastern Europe. This paper examines the ways in which supply strategy is likely to change. We show that both market growth and improved market accessibility will lead the external firms to switch from exporting to foreign direct investment. However, market growth is likely to lead to dispersed investment in the growing economies, whereas increased market accessibility, by establishing an integrated regional bloc in Eastern Europe, is more likely to lead to concentrated investment plus infra-regional exports to the remainder of the regional bloc. The switch from exporting to local production through foreign direct investment will favor consumers through lowered prices but will harm national producers by depressing profit margins.     

Efficiency Measurement in Network Industries: Application to the Swiss Railway Companies

The persistence of increasingly high government subsidies in Switzerland’s railroads has led the federal and cantonal authorities to discussing the possibility of high-powered incentive contracts such as those based on cost efficiency benchmarking. Railways are however, characterized by a high degree of unobserved heterogeneity that could bias the efficiency estimates. This paper examines the performance of several panel data models to measure cost efficiency in network industries. The unobserved firm-specific effects and the resulting biases are studied through a comparative study of several stochastic frontier models, applied to a panel of 50 railway companies operating over a 13-year period.* The authors wish to thank Michael Crew and two anonymous referees for their helpful suggestions.

Selective Schools

This paper studies how schooling admission tests affect economic performance in an economy where individuals are endowed with both academic and non‐academic abilities and both abilities matter for labour productivity. We develop a simple model with schools run by the goverment, where individuals signal their abilities by taking an admission test and sort into low quality and high quality schools. When abilities are poorly correlated in the population, as documented in the literature, a standard test based only on academic abilities can be less efficient than a balanced test, which considers both ability types. We show that a sequential testing strategy, with schools testing academic abilities and firms testing non‐academic abilities on the sub‐sample of graduates of high quality schools, does not necessarily replicate the outcome of a balanced test.     

Supply uncertainty of the bond investor base and the leverage of the firm

We examine the effect of the bond capital supply uncertainty of institutional investors (e.g., mutual bond funds and insurance companies) on the leverage of the firm using a novel data set. Our main finding is that the supply uncertainty of the firm's bond investor base — measured as (i) the average portfolio turnover, or (ii) the average flow volatility of investors holding the firm's bonds, or (iii) the prevalence of mutual funds among the firm's bondholders as opposed to insurance companies — has a negative and significant effect on the leverage of the firm. The supply uncertainty of the firm's bond investor base also has a negative and significant effect on the firm's probability of issuing bonds, and a positive and significant effect on the firm's probability of issuing equity and borrowing from banks. We take a multi-pronged approach to address potential endogeneity issues, including use of geography-based instruments and firm fixed effects, subsample analyses, and a placebo test. Our results highlight the fragility of access to the bond market for companies that depend on mutual funds with high turnover/ flow volatility as primary bond investors.     

Stock prices and money velocity: a multi-country analysis

What kind of information do stock prices offer for predicting velocity? This paper develops previous work by Milton Friedman for the US economy and shows that in a panel of 25 countries a wealth effect derived from the stock market has negatively influenced the ratio of nominal income to a broad definition of money. Taking quarterly data for the period 1961–1998, the relationship holds in Japan, the UK and Switzerland; in Italy a substitution effect (away from money) has also been operating. Overall, these empirical findings indicate the presence of systematic influences of stock price fluctuations on money velocity and suggest that the repercussions of asset inflation and deflation on the behavior of monetary aggregates should be monitored.
