The structure of the set of sunspot equilibria in economies with incomplete financial markets

Summary This paper considers the set of equilibria of two-period, sunspot economies withS purely extrinsic states of nature in the second period andI assets with linearly independent nominal payoffs. The span of the payoff matrix contains the vector [1, ... , 1] (i.e., inside money). The set of economies is described in terms of (sunspot-invariant) utility functions. IfS>I> 0, there is an open, dense set of economies such that, given a vector of no arbitrage asset prices, the set of equilibrium allocations contains a smooth manifold of dimensionS—I. Such a manifold contains at least one nonsunspot equilibrium (and at most a finite number of such equilibria).The paper was written while I was a visitor at C.O.R.E., Universitè Catholique de Louvain, with the financial support of a S.P.E.S. fellowship. I would like to thank D. Cass, H. Polemarchakis and P. Siconolfi for their helpful comments.     

Seasonal and Day-of-the-Week Effects in Four Emerging Stock Markets

The “January effect” and the “weekend effect” have proven to be persistent anomalies in U.S. equity markets. The objective of this paper is to examine seasonal and daily patterns in equity returns of four emerging markets: Hong Kong, Singapore, Malaysia, and the Philippines. These markets are gaining importance with the globalization of business; therefore, it is necessary to examine the efficiency and functioning of these capital markets. Our analysis uses daily data for the 12 years from September 1, 1976, to June 30, 1988. The results support the existence of a seasonal pattern in these markets. Returns in the month of January are higher than any other month for all markets examined except the Philippines. A robust day-of-the-week effect is also found. These markets exhibit a weekend effect of their own in the form of low Monday returns. In addition, there exists a strong “Tuesday effect,” which may be related to the + 13 hour time difference between New York and these emerging markets.     

Some consequences of banks' LDC loans: A note

The realized returns on LDC loans made prior to 1980 and hypothetically sold at (below par) secondary market prices in either 1986, when a secondary market first began, or, say, in 1989 are moderately positive. The realized risk-adjusted returns to investors on a portfolio of large LDC lending bank stocks are unmistakenly lower than the return on a broad market index, though they are not significantly so. Similarly, although the difference is not statistically significant, the average realized return on LDC lending banks' stocks is well below that of a portfolio of non-LDC lending banks. The article concludes that while shareholders suffered economic losses as a result of LDC lending activity, these losses were not quantitatively large.     

Welfare and excess volatility of exchange rates

We study the properties of a GEI model with nominal assets, outside money (injected into the economy as in Magill and Quinzii (J Math Econ 21:301–342, 1992)), and multiple currencies. We analyze the existence of monetary equilibria and the structure of the equilibrium set under two different assumptions on the determination of the exchange rates. If currencies are perfect substitutes, equilibrium allocations are indeterminate and, generically, sunspot equilibria exist. Generically, given a nonsunspot equilibrium, there are Pareto improving (and Pareto worsening) sunspot equilibria associated with an increase in the volatility of the future exchange rates. We interpret this property as showing that, in general, there is no clear-cut effect on welfare of the excess volatility of exchange rates, even when due to purely extrinsic phenomena.     

Trade and revelation of information

We consider an economy with asymmetric information and two types of agents, fully informed and uninformed. Uninformed agents update their information observing equilibrium prices and the equilibrium levels of other agents’ excess demand. We show that, for a generic set of economies, there are rational expectations equilibria which are partially revealing on an open, dense set of signals of positive Lebesgue measure, provided that the dimension of the signal space is sufficiently larger than the dimension of the commodity space.     

Investments in education and welfare in a two-sector,random matching economy

We consider a random matching model where heterogeneous agents choose optimally to invest time and real resources in education. Generically, there is a steady state equilibrium where some agents, but not all of them, invest. Regular steady state equilibria are constrained inefficient in a strong sense. The Hosios (1990) condition is neither necessary nor sufficient for constrained efficiency. We also provide restrictions on the fundamentals sufficient to guarantee that equilibria are characterized by overeducation (or undereducation), present some results on their comparative statics properties, and discuss the nature of welfare improving policies.     

Labor Standards in the Global Economy: Issues for Investors

In the mid-1990s, global labour standards emerged as a new and important are of concern for socially responsible investors, especially with respect to investments in the "problematic" footwear, apparel, and toy industries. In this paper, I elucidate the primary areas of concern for investors and discuss a framework for evaluating firms' labor standards performance. In addition, I argue that today's sweatshop debates follow closely those of centuries ago, with the standard economic defense of low wage manufacturing on the one hand, and the activists' protests against poor conditions and wages on the other. An examination of this historical context reveals a promising middle ground in this ongoing debate.     

The Role and Current Status of IFRS in the Completion of National Accounting Rules – Evidence from Italy

Abstract

We examine the recent changes that have affected the Italian accounting scenario after the adoption of the IFRS and the enactment of the European accounting system. In particular, we have focused our attention on the decision of the legislature to enlarge the mandatory adoption of IFRS to non-listed companies and to individual financial statements (FS). At the same time, we have observed the changes determined by the EU Directive 2013/34 on the Italian Civil Code and the FS legislation. Both set of changes are describing a process under which the Italian accounting rules are moving towards the international accounting standards and their framework, contents and methods. Therefore, the main differences among national rules and IFRS are grounded on the measurement rules and the role played by the historical cost principles and the strict and detailed regulation of the Balance sheet and Income statement formats.
