Measuring the Cost‐Effectiveness of an R&D Tax Credit for the UK

This paper investigates the economic impact of the government's proposed new UK R&D tax credit. We measure the benefit of the credit by the effect on value added in the short and long runs. This is simulated from existing econometric estimates of the tax‐price elasticity of research and development (R&D) and the effect of R&D on productivity. For the latter, we allow R&D to have an effect on technology transfer (catching up with the technological frontier) as well as innovation (pushing the frontier forward). We then compare the increase in value added to the likely exchequer costs of the programme under a number of scenarios. In the long run, the increase in GDP far outweighs the costs of the tax credit. The short‐run effect is far smaller, with value added only exceeding cost if R&D grows at or below the rate of inflation.     

Acceptance of China Research in Western Accounting Journals (1978-2007)

This study provides a statistical analysis of the research involving mainland China accepted in Western accounting journals in the past thirty years (1978-2007). The analysis focuses on assessing the level of acceptance of China research and examining the publication patterns of these studies. Based on the results, the study then explores factors explaining the findings, and provides critical assessments on the status quo of China research, suggestions to cope with current problems, and suggestions to promote China research.

Human capital and economic development

This paper develops a general equilibrium model of fertility and human capital investment with young adult mortality. Because young adult mortality is negatively related to average young adult human capital, human capital accumulation lowers mortality, inducing demographic transition and industrial revolution. Data confirm that young adult mortality is related negatively to schooling, and the rate of return to schooling, and positively to fertility. The data indicate a negative relationship between TFP growth and schooling accumulation. The model fits the data on country populations, per capita incomes, human capital, total fertility rates, infant mortality, life expectancy and conditional life expectancy.     

Capital controls and covered interest parity in the EU: Evidence from a panel-data unit root test

Capital Controls and Covered Interest Parity in the EU: Evidence from a Panel-Data Unit Root Test. - This paper examines whether the abolition of the remaining capital controls in the EU during 1990 has facilitated the achievement of onshore covered interest parity with respect to Germany. We test for unit roots in covered interest differentials. However, we employ the new methodology of pooling our data and performing a unit root test based on a panel data set. Our results suggest that the period characterized by the absence of capital controls has not facilitated the achievement of covered interest parity. Indeed, evidence in favour of covered interest parity is strongest for the period preceding 1990.     

Reconciling Bagehot and the Fed's Response to September 11

Bagehot (1873) states that to prevent bank panics a central bank should provide liquidity at a "very high rate of interest." In contrast, most of the theoretical literature on liquidity provision suggests that central banks should lend at an interest rate of zero. This is broadly consistent with the Federal Reserve's behavior in the days following September 11, 2001. This paper shows that both policies can be reconciled. With commodity money, as in Bagehot's time, liquidity is scarce and a high price allows banks to self-select. In contrast, the Fed has a virtually unlimited ability to temporarily expand the money supply so self-selection is unnecessary.

Funded pensions and intergenerational and international risk sharing in general equilibrium

We explore intergenerational and international risk sharing in a general equilibrium multiple-country model with two-tier pensions systems. The exact design of the pension system is key for the way in which risks are shared over generations. The laissez-faire market solution fails to provide an optimal allocation because the young cannot share in the financial risks. However, the existence of wage-indexed bonds combined with a pension system with a fully funded second tier that pays defined wage-indexed benefits can reproduce the first best. If wage-indexed bonds are not available, mimicking the first best is not possible, except under special circumstances. We also explore whether national pension funds want to deviate from the first best by increasing domestic equity holdings. With wage-indexed bonds this incentive is absent, while there is indeed such an incentive when wage-indexed bonds do not exist.     

Entry deterrence and experimentation under demand uncertainty

We examine the effect of a threat of entry on experimentation about demand by an incumbent monopolist when there is a fixed cost of entry. We show that experimentation may itself be used as a tool for entry deterrence and derive conditions under which experimentation reduces the probability of entry. These conditions depend on the entry rule which in turn depends on entry costs. We show that if experimentation does not deter entry, the monopolist incumbent experiments less. We also characterize experimentation and entry in the linear-uniform example, and show that cost of entry and experimentation do not have a monotonic relationship.     

The success of divestitures in merger enforcement: Evidence from the J&J-Pfizer transaction

Despite being a widely used tool in merger enforcement, there have been few studies of whether antitrust divestitures are successful. We help fill this void by conducting a study of the divestitures relating to Johnson & Johnson's $16.6 billion acquisition of Pfizer's consumer health division in 2006. Six brands were divested in this matter to alleviate antitrust concern. For three of the brands, their pre- and post-divestiture performances are similar, while the remainder underwent changes that do not appear to be divestiture related. Overall, the results are consistent with the view that the divestitures maintained the pre-transaction level of competition.
