Investment Horizon and Composition of Optimal Portofolio: International Evidence

Little attention has been paid in the literature to the impact of different investment horizons on the portfolio compositiondespite its importance to portfolio managers. One exception isthe study by Gunthorpe and Levy (1994) on the U.S. stock market.Our paper extends the same study to the stock markets of Japan,Hong Kong and Korea. Using 40 individual stocks in each market,our results support those of Gunthorpe and Levy (1994) in thatthe composition of an optimal portfolio depends heavily on theinvestment horizon. When the investment horizon lengthens, theproportion of defensive stocks becomes larger while that ofaggressive stocks becomes smaller.     

Impact of Consumer Installment Debt on Food Expenditures

Trends in consumer installment credit over the period 1980 to 1989 are discussed; as well, a two-equation recursive model is developed to identify and assess the impact of installment credit on food expenditures. The first equation concerns factors affecting the ratio of consumer installment credit to personal disposable income, namely habit persistence, expected income, the prime interest rate, the unemployment rate, and the percentage of the population aged 25 to 44. The second equation focuses on factors affecting real per capita food expenditures, namely the real price of food, real per capita personal disposable income, seasonality, and a polynomial distributed lag of the measure of the ratio of consumer installment credit to personal disposable income from the first equation. The ratio of installment credit to personal disposable income has a positive effect on food expenditures; over the long run a one percent change in this ratio leads to a 0.15 percent change in real per capita food expenditures. On average, it takes just over six months for a change in this ratio to be transferred to food expenditures.     

Estimating the Divisional Cost of Capital: An Analysis of the Pure-Play Technique

This paper suggests that the pure-play technique can be used in conjunction with the capital asset pricing model to determine the cost of equity capital for the divisions of a multidivision firm. Since the beta for a division is unobservable in the marketplace, a proxy beta derived from a publicly traded firm whose operations are as similar as possible to the division in question is used as the measure of the division's systematic risk. To provide empirical support for using the pure-play technique, a sample of multidivision firms and pure-play associated with each division is examined. It is shown that an appropriately weighted average of the betas of the pure-play firms closely approximates the beta of the multidivision firm.     

Analysis of the 1980 Sydney Survey of Work Patterns of Married Women: Further Results*

Using cross-section data from the 1980 Sydney survey of the work patterns of married women, this paper contributes to the very scarce Australian stock of disaggregate econometric studies of the labour market activities of married women. Labour force participation, hours of work and wage functions (reservation wage as well as market wage) are estimated in a second-generation static labour supply framework. Unique features of the study include the availability of direct data on previous market experience, a formulation of the impact of children on the participation decision which permits testing for the presence of economies of scale in child-minding activities, estimation of the reservation wage function, and a data base which permits a clear distinction between earnings and other forms of income.     

COMPARING POST-COLD WAR MILITARY CONVERSION IN THE UNITED STATES AND RUSSIA

According to the conventional wisdom, military conversion in Russia would be more difficult than in the United States because Russia does not have the developed market infrastructure and institutions that help western defense firms redeploy resources for civilian production. A closer look raises doubts about these arguments. Western defense firms have had difficulties with conversion because they cannot compete with the existing relatively efficient civilian firms. Meanwhile, the principal competitors of the Russian defense firms, the large Russian civilian enterprises, are closer in nature to defense enterprises than to efficient market firms. While this does not bode well for the Russian economy in general, the defense enterprises should not find themselves at a significant disadvantage in the civilian markets. Two effects can be distinguished. On the one hand, due to the more developed market infrastructure, the U.S. economy is presumably good at redeploying defense-related resources across firm boundaries. On the other hand, the large and efficient civilian sector in the United States makes the marginal "civilian" value of the redeployed resources low. It is the interaction of these factors, rather than the degree of development of market infrastructure alone, that determines the relative difficulty of military conversion. Additionally, empirical evidence based on regional data indicates that despite enormous defense expenditure cuts, the economic performance of Russia's regions is only relatively weakly correlated with the regions' dependency on defense industry.     

Project Labor Agreements' Effect on School Construction Costs in Massachusetts

This paper investigates the impact of Project Labor Agreements (PLAs) on school construction cost in Massachusetts. Although simple models exhibit a large positive effect of PLAs on construction costs, such effects are absent from more completely specified models. Further investigation finds sufficient dissimilarity in schools built with and without PLAs that it is difficult to distinguish the cost effects of PLAs from the cost effects of factors that underlie the use of PLAs.     

Voluntary Disclosure and Equity Offerings: Reducing Information Asymmetry or Hyping the Stock?*

We examine corporate disclosure activity around seasoned equity offerings and its relationship to stock prices. Beginning six months before the offering, our sample issuing firms dramatically increase their disclosure activity, particularly for the categories of disclosure over which firms have the most discretion. The increase is significant after controlling for the firm's current and future earnings performance and tends to be largest for firms with selling shareholders participating in the offering. However, there is no change in the frequency of forward‐looking statements prior to the equity offering, something that is expressly discouraged by the securities law. Firms that maintain a consistent level of disclosure experience price increases prior to the offering, and only minor price declines at the offering announcement relative to the control firms, suggesting that disclosure may have reduced the information asymmetry inherent in the offering. Firms that substantially increase their disclosure activity in the six months before the offering also experience price increases prior to the offering relative to the control firms, but suffer much larger price declines at the announcement of their intent to issue equity, suggesting that the disclosure increase may have been used to “hype the stock” and the market may have partially corrected for the earlier price increase. Firms that maintain a consistent disclosure level have no unusual return behavior relative to the control firms subsequent to the announcement, while the firms that “hyped” their stock continue to suffer negative returns, providing further evidence that the increased disclosure activity may have been hype, and suggesting that the hype may have been successful in lowering the firms' cost of equity capital.     

A TEST OF EMPLOYER DISCRIMINATION IN THE NBA

This paper presents a test of an important implication of Becker's theory of employer discrimination: when institutional change enhances labor mobility, employer discrimination falls because it becomes more costly for employers to indulge tastes for discrimination. The test case is the National Basketball Association (NBA). This paper specifically addresses the following question about the NBA: why did black/white player salary differentials vanish by the early 1990s? Previous studies claim that NBA wage gaps in the 1980s are attributable to customer discrimination and monopsonistic wage discrimination. This study argues that employer discrimination was an important source of those gaps and that one reason they vanished was because reduced monopsony power eradicated employer discrimination. Monopsony power fell because the 1988 NBA Collective Bargaining Agreement and the entry of four new teams in the league enhanced player mobility and increased the amount of labor market competition. Using data for the 1985-86 and 1990-91 seasons, employer discrimination was proxied by the race of the team's general manager. Empirical results strongly suggest that a major reason the NBA wage gap vanished in the later period was because of a reduction in employers' ability to discriminate. This is in contrast to earlier literature on the NBA, which has tended to emphasize the role of customer discrimination. (JEL J71)     

Migrants Encounter Migrants in the City: the Changing Context of ‘Home’ for Second‐Generation Greek‐American Return Migrants

This article looks at the ‘return’ migration of second‐generation Greek Americans to their parents’ homeland, Greece. It is based on interviews with, and written accounts supplied by, 40 participants in the research, all now living in the Athens region. The article addresses two main sets of questions. First, why do they relocate to Greece, what are they looking for, and how do they cope with difficulties and disappointments? Second, and more specifically, how do they react to the fact that Greece is no longer a homogenous hellenistic society, but has become in recent years a de facto multicultural one due to the presence of hundreds of thousands of immigrant workers and their families? Three hypotheses are proposed for this inter‐migrant encounter: returnees, shocked by the ‘new immigration’, view it negatively as upsetting the ‘pure Greek’ homeland they had hoped to find; returnees are more sympathetic because of their own families’ history as immigrants in multicultural America; and returnees differentiate themselves as ‘good’ migrants from Greece’s immigrants who are constructed as ‘bad’ migrants. Evidence from the migrants’ testimonies is found to support all three hypotheses; however, there is more support for the second one. In addition, a fourth outcome was voiced: that of discrimination against Greek Americans who are made to feel, in certain circumstances, outsiders by the ‘true’ Greeks. Suggestions are made for further comparative research.
