APT VS. CAPM ESTIMATES OF THE RETURN-GENERATING FUNCTION PARAMETERS FOR REGULATED PUBLIC UTILITIES

In public utility rate hearings, there are extensive arguments concerning the most appropriate model of the return-generating function. Bower, Bower, and Logue (1984) suggest that the APT is superior to the CAPM, but their results have troublesome ranking differences between the two models when applied to returns from electric versus natural gas utilities. The purposes of this paper are to develop forward estimates of the parameters for both of these models applied to five different utility portfolios of electric and natural gas companies at a point in time, and to test whether these estimates are valid during a subsequent or future period. Also, forecasting errors for each model are compared to determine which model is best and to ascertain if there are any ranking conflicts. There are no ranking conflicts with the models as the market model consistently underestimates the actual return. Thus, the analysis suggests that the arbitrage model is a superior representation of the return-generating process of these utilities.     

Reserve funds key to keeping health plans fiscally fit

To avoid an economic roller coaster ride, plan sponsors should establish an appropriate financial reserve during the good times to provide a safety net during the bad. Because no law expressly requires multiemployer health funds to maintain reserves, each fund's needs should be determined by its trustees, in consultation with professional advisors. This article explores the role of reserves in helping plans to prepare for various needs and contingencies.     

Price Interactions in a Sequential Global Market: Evidence from the Cross-listed Stocks

In this paper, we investigate the pattern of dynamic interactions among the prices of those stocks that are cross-listed on the three major stock markets of the world, i.e. New York, London and Tokyo. Major findings are: first, regardless of the nationality of stocks, innovations in the 'home' market returns are always fed into the returns in the 'overseas' markets, with the former causing the latter in the Granger sense. However, innovations in the New York market returns of foreign stocks are fed back into their respective home markets, contributing to the price discovery there. Second, the 'succeeding' overseas market, which operates immediately after the home market, plays a dual-role: it conducts the home market innovations to the next-opening overseas market, as well as adds its own innovations. Third, the exchange rate changes substantially influence the overseas market returns, but not the home market returns. The exchange rates appear to play a role in the transmission mechanism mainly via the inter-market price parity.     

The generic existence of rational expectations equilibrium in the higher dimensional case

The study of the generic existence of rational expectations equilibrium has concentrated on three cases, according to whether the space of “states of private information” has dimension less than, equal to, or greater than the price space. Previous results have shown that in the first case fully revealing equilibria exist generically and in the second case there are open sets of environments with no equilibrium. This paper shows that in the third case there is a residual set of environments which permits equilibria which are arbitrarily close to fully revealing.     

Does Intra‐regional Trade Matter in Regional Stock Markets? New Evidence from the Asia‐Pacific Region

We provide new evidence on the relationship between bilateral trade and stock market returns across the Asia‐Pacific region. Using three country blocs in this region, including the Far Eastern bloc, the Chinese bloc and the Australian bloc, we examine whether trade linkages between countries affect their stock returns. Incorporating two distinct dynamic properties of regime shifting and cointegration in intra‐regional trade and stock market returns, we employ the newly suggested multivariable smooth transition autoregressive vector error correction model (STAR‐VECM). A series of estimations reveals evidence that bilateral trade significantly Granger‐causes stock returns in the Asia‐Pacific region, with effects that are asymmetric depending upon the stock market regime and the country pair. Among the three blocs, the Far Eastern bloc displays a more pronounced positive effect of bilateral trade growth on stock returns than do the other blocs.     

Owner-managers and firm performance during the asian and global financial crises: evidence from Korea

We examine the performance of the Korean owner-managers during the 1997?1998 Asian financial crisis and the 2008?2009 global financial crisis to establish whether they overcome the unexpected exterior shocks better than employed managers. We find that the owner-managers record a significantly greater performance during the crises, and especially during the latter period. Moreover, our results suggest that such a tendency comes from the owner-managers’ superior investment decisions. Our paper thus highlights the role of owner-managers by studying their performance during the Korean economic crisis periods. (JEL G01, G32, G34)
