Trembles in extensive games with ambiguity averse players

We introduce and analyze three definitions of equilibrium for finite extensive games with imperfect information and ambiguity averse players. In a setting where players’ preferences are represented by maxmin expected utility, as characterized in Gilboa and Schmeidler (J Math Econ 18(2):141–153, 1989), our definitions capture the intuition that players may consider the possibility of slight arbitrary mistakes. This generalizes the idea leading to trembling-hand perfect equilibrium as introduced in Selten (Int J Game Theory 4(1):25–55, 1975), by allowing for ambiguous trembles characterized by sets of distributions. We prove existence for two of our equilibrium notions and relate our definitions to standard equilibrium concepts with expected utility maximizing players. Our analysis shows that ambiguity aversion can lead to behavioral implications that are distinct from those attained under expected utility maximization, even if ambiguous beliefs only arise from the possibility of slight mistakes in the implementation of unambiguous strategies.     

Joint outputs and real wage rates

The magnification effect in standard international trade theory asserts that if the relative price of the labor-intensive commodity increases, the real wage will also increase, as will the wage/rental ratio. This result depends upon the assumption that both activities are nonjoint—each combining labor and capital to produce a single output, so that if activities are joint instead, the results are in jeopardy. It is shown that if the difference between the share of commodity one produced in the first activity and in the second activity exceeds the difference between the labor distributive shares in the first activity and the second, an increase in commodity 1's relative price raises the wage/rental ratio. The real wage unambiguously rises in this case if and only if the ratio of the commodity output shares in the two activities exceeds the ratio of labor shares.     

Sustainability of A Pay‐as‐you‐Go Pension System in A Small Open Economy with Ageing,Human Capital and Endogenous Fertility

The aim of the article is to theoretically investigate if a pay‐as‐you‐go (PAYG) pension system is sustainable in the presence of a declining population and increasing longevity of the retired generation. For this purpose, we use an overlapping generation model with endogenous fertility, endogenous longevity and human capital accumulation in a small open economy. We find that pensions will always increase as long as it is beneficial for parents to invest in human capital. Furthermore, we get the result that the ratio between pension benefits and the consumption of the young generation will strive to a positive limit value, and that a pure PAYG pension system will not run into any solvency problem due to a decreasing fertility rate or ageing.     

Tax Rules and the Sale and Leaseback of Corporate Real Estate

This study examines the effect of the sale and leaseback of corporate real estate on the stock prices of the selling firms. We ask whether the Tax Reform Act of 1986 (TRA 1986) had a negative impact on the market valuation effects of corporate sale and leasebacks. The results of the comparative statics analysis predict that the net present value of the lessee should be negatively related to the tax depreciation recovery life for the lessor and to the marginal ordinary income tax rate of the marginal holder of commercial mortgage debt. However, it should be positively related to the marginal tax rate of the equityholder of the corporate lessee. Changes in the marginal ordinary income tax rates of the lessor and the corporate lessee have an ambiguous effect on the equity value of the corporate lessee. Nevertheless, results of simulation analyses suggest that the relationship between the net present value of the lessee and each of the tax rates of the lessor and corporate lessee is negative. The empirical evidence suggests that subsequent to TRA 1986, the lessee's benefits associated with sale and leaseback transactions have decreased.     

The effect of business taxation on the location of industry

A theoretical and econometric model is specified which permits the estimation of the effect of local taxes on economic activity in a locality. A location elasticity of ?0.35 is found for manufacturing activity in New York City with respect to business taxes, while no significant elasticity is found for nonmanufacturing activity. The deadweight losses and revenue effects of the tax are analyzed and calculated, as are the optimal second-best taxes for a locality.     

The Effects of Bilateral Tax Treaties on U.S. FDI Activity

The effects of bilateral tax treaties on FDI activity have been unexplored, despite significant ongoing activities by countries to negotiate and ratify these treaties. This paper estimates the impact of bilateral tax treaties using both U.S. inbound and outbound FDI over the period 1980–1999. Robust to a wide variety of alternative specifications, we find little evidence that bilateral tax treaties increase FDI activity, contrary to OECD-stated goals for such treaties.     

Economic Consequences of the Cancellation of Inner Reserves for Hong Kong Banks

Inner reserves, which allow banks to report a higher or lower earnings at managerial discretion, bring into focus the ability of the market to make an informed judgment of banks' performance. This study examines the market response to the disclosure and elimination of inner reserves by Hong Kong banks resulting from a change in the regulatory reporting system. Test results show that despite a significant increase in the variability of bank earnings in the post-compared to the pre-disclosure period, there is no evidence of a significant increase in banks' systematic risk in the post-disclosure period. Earnings-returns association is significantly stronger in the post- than in the pre-disclosure period, indicating an improvement in the value relevance of reported earnings. Disclosure of inner reserve transfer is found to provide incremental information over reported earnings over a short disclosure window. These results suggest that the increased value relevance of earnings outweighs the costs of inner reserve cancellation, thus supporting greater reporting transparency for Hong Kong banks.
