Joskow (1987) examined the importance of specific investments to the contract duration of coal contracts. Since different price-adjust mechanisms are also adopted and provide different incentives during a long-term relationship, this paper examines how the level of specific investments affect...

Medical providers' profit considerations might take priority over their patients' needs in Taiwan because they are allowed to both dispense and prescribe medications. I examine this problem in the demand of the anti-diabetic drugs market using information from millions of claims. Empirical...

Global budgeting sets a predetermined cap to restrain health expenditure, but the fixed budget for medical providers could result in less efficient services. This paper measures hospital efficiency under global budgeting using simultaneous stochastic frontier analysis, stressing that physicians...

This study provides a new explanation of total factor productivity growth of Taiwanese industry. Besides the channels identified in the literature, this study finds that the venture capital (VC) industry development significantly promotes productivity growth. In addition, an indicator of legal...

Physicians’ generic pharmaceutical adoption involves not only patients’ and insurance payers’ cost, but also their own interests. This study examines this double agency problem for physicians by using Taiwanese data because two of its institutional features: First, patients and physicians...

This paper develops the identification and estimation of nonlinear semi-parametric panel data models with mismeasured variables and their corresponding average partial effects using only three periods of data. The past observables are used as instruments to control the measurement error problem,...

This paper provides sufficient conditions for the nonparametric identification of the regression function m(.) in a regression model with an endogenous regressor x and an instrumental variable z. It has been shown that the identification of the regression function from the conditional...

This paper considers nonparametric identification of nonlinear dynamic models for panel data with unobserved voariates. Including such unobserved covariates may control for both the individual-specific unobserved heterogeneity and the endogeneity of the explanatory variables. Without specifying...

This paper provides a test for completeness in a class of nonparametric specification with an additive and independent error term. It is known that such a nonparametric location family of functions is complete if and only if the characteristic function of the error term has no zeros on the real...
