Demographics and the long-horizon returns of dividend-yield strategies

This paper investigates the relationship between demographic changes and the long-run returns of dividend-yield investment strategies. We hypothesise that in a world where components of wealth are mentally treated as being non-fungible, the preference for high dividend-paying stocks by older investors means that the excess returns of high dividend-yielding stocks, relative to other stocks, should be positively related to demographic clientele variation. In particular, we find that, consistent with the behavioural life-cycle hypothesis, long-run returns of dividend-yield investment strategies are positively driven by changes in the proportion of the older population. Our results are robust when controlled for the Fama–French factors, inflation rate, consumption growth rate, interest rates, tax clienteles, time trend and alternative definitions of both dividend-yield strategies and demographic variation.     

Technological Progress versus Efficiency Gain in Manufacturing Sectors

This study decomposes the nonparametric Malmquist productivity index for 36 Korean manufacturing sectors into two components: technological change and technical efficiency change. The empirical results show that while each sector displays quite different growth patterns, productivity growth is dominated by technological change. Technological change is found to have a negative correlation with efficiency change. Secondary regression performed in this study identifies the relationship between productivity growth measures and several key policy variables, such as effective protection rate, market concentration, and so forth. The productivity estimates are compared with those of the conventional Törnqvist productivity index.

Using Market Structure to Regulate a Vertically Integrated Monopolist

A natural monopolist whose cost is private information produces a good which is combined with another good that can be produced by the monopolist or by other firms. The agency that regulates the monopolist can impose any of several different market structures in the industry: integrated monopoly, vertical separation with free entry downstream, or liberalization downstream (both integrated and independent production). When several firms produce downstream, a Cournot quantity-setting game with free entry determines the market price. We derive the optimal contracts to offer the monopolist under all three market structures and examine the influence of downstream cost differences on access prices.We then study the optimal regulatory policy where the regulator can condition the downstream market structure on the monopolist's cost report to the regulator. The optimal regulatory policy awards a monopoly to a low-cost upstream firm, but requires free entry downstream if the monopolist reports high upstream costs. Thus, the choice of market structure is an additional tool to limit rent extraction by the monopolist. Simulation analysis reveals the possibility of significant welfare gains from this additional regulatory tool.     

HYSTERESIS IN UNEMPLOYMENT REVISITED: EVIDENCE FROM PANEL LM UNIT ROOT TESTS WITH HETEROGENEOUS STRUCTURAL BREAKS

This paper applies the panel LM unit root tests with heterogeneous structural breaks in level by Im  et al. ( Oxford Bulletin of Economics and Statistics , 67 (2005), pp. 393–419) to re-examine the validity of hysteresis in the unemployment rates of 19 OECD countries. Our empirical findings are favourable to the stationarity of the unemployment rates, i.e., the unemployment hysteresis hypothesis is strongly rejected. Our results suggest that shocks to unemployment rates are temporary and soon converge when we control for breaks. A major policy implication of the study is that a fiscal or monetary stabilization policy would not have permanent effects on the unemployment rates of the 19 OECD countries.     

The role of e-Health in the changng health care environment

In 2005 health care organizations spent 2.3% of total operating expenses on information technology and are slowly developing the infrastructure necessary to expand e-Health capabilities. E-Health is being recognized as a method to improve the overall health status of the population. It is important to build partnerships among health care providers, local community organizations, and national health care associations to ensure the continued development of e-Health initiatives. This study has managerial implications associated with the strategic application of e-Health systems and policy implications on future resource allocation.
