摘要：The oft-observed inverse relationship between farm size and productivity has elicited several explanations having important policy and theoretical implications. Using advances in the analysis of price risk effects on producer behavior, and a simple two-period model of an agricultural household that both produces and consumes under price uncertainty at the time labor allocation decisions are made, this paper demonstrates analytically that a non-degenerate land distribution and price risk can to...

摘要：This note is an attempt to explore two issues: (1) the trend of interprovincial inequality in the post-1978 reform era in China; and (2) the factors behind the dynamics of interprovincial inequality. Using recently released provincial gross domestic product (GDP) data, we have shown that interprovincial inequality decreased in the first half of the 1980s, but started to increase in the second half of the 1980s. To understand the impact of sectoral reforms on interprovincial inequality, the ove...

摘要：By influencing the incentives to innovate, intellectual property rights protection may affect economic growth in important ways. An important question for many countries is whether stricter enforcement of intellectual property is a good strategy for economic growth. This paper examines the role of intellectual property rights in economic growth,utilizing cross-country data on patent protection, trade regime, and country-specific characteristics. The evidence suggests that intellectual property...

摘要：A food demand system is proposed based on demand for energy, variety, and tastes of foods. By specifying utility as an explicit function of these characteristics, the entire matrix of demand elasticities can be derived for a foods and one non-food from prior specification of just four elasticities, while avoiding any assumption of separability between foods. This framework can explain why poorest groups often are most price-responsive, but also can account for highest price-responsiveness by m...

摘要：This paper focuses on measuring the relative importance of the role of technology versus that of institutional innovation in China's rural economy, A six-equation rice sector model explaining provincial-level technology adoption, yield, and factor demand are econometrically estimated using data from China's 13 rice growing provinces for the period 1975-90, Growth decomposition analysis identifies technology adoption as the most important determinant of rice yield growth during 1978-84, account...

摘要：A model of credit markets in which there is a costly-state-verification problem is integrated into a neoclassical growth model. The presence of a credit market friction gives rise to credit rationing, which in turn impacts on the growth path of an economy. The model delivers predictions about the co-movements between per capita income, credit rationing, interest rates, and factor prices. The implications of the model are generally empirically supported in U.S. and Taiwanese data. The model als...

摘要：In a static perfectly competitive model, it is well understood that a quota license has a scarcity value. In a dynamic setting with uncertainty, the license price has two additional components, both of which arise from the fact that the license is valid for an entire year. They are the asset market component and the option value component. In this paper, we construct a model of the quota license market in which the license demand and supply functions incorporate these various components, and e...
