钱包赌戏悖论及其行为的经济学意义

本文对行为经济学的一个重要微观模型———钱包赌戏悖论建立了认知分析框架 ,不仅彻底消解了该悖论 ,还发现了与效用和概率均无关的一种新的非理性效应。这一效应既可能导致无帕累托效率的交易陷阱 ,也可能与效用歧化和概率误判等已知的行为经济学效应协同作用 ,产生更复杂的非理性决策。     

The amenity value of woodland in Great Britain: A comparison of economic estimates

Forests produce benefits over and above the revenue yielded from timber and other wood based products. Most important among these may be the recreational benefits for visitors, which have been examined in several studies. Total benefits for residents are perhaps more accurately captured in property values since, ceteris paribus, the price of a house reflects willingness to pay to live near an environmental amenity such as a forest to gain access to it, and also the amenity (non-use) value of the forest in so far as it creates a pleasant landscape. However, the total non-priced value of forestry is not the sum of HPM and ITCM benefit estimates. Recreational benefits will typically be less, and will be subsumed in the HPM estimates, since the hedonic price is partly induced by the value of recreational access.

From T-Bills to Stocks: Seasonal Anomalies Revisited

This paper employed eleven data series which consist of stocks, bonds, bills, equity premiums, term premiums, and various default premiums to investigate whether January seasonality reported in existing literature is robust across different states of the economy as this has important trading implications. For the periods 1926–1990, small stocks, small stock premiums, low grade bonds, and default premiums (spread between high grade, low grade and government bonds) reveal January seasonality and that the seasonality is robust across different states of the economy except for low grade bond returns and default premiums. January seasonality for low grade bond returns and low grade bond default premiums are primarily driven by results found during periods of economic expansion. Overall, January seasonality is more evident during the economic expansion periods although the magnitude of default premiums is larger during periods of economic contraction. Furthermore, prior findings of strong summer equity returns are primarily driven by the results found during the periods of economic contraction. It is also found that equity returns are generally higher during periods of economic expansion.     

Price Rigidity and the Selection of the Exchange Rate Regime

We evaluate and qualify Friedman's, 1953, “case for flexible exchange rates” in the presence of sticky prices in a two country model. We find that a flexible regime performs indeed better when the degree of nominal price rigidity is high while a bilateral peg does better when prices are fairly flexible. This result obtains independent of whether monetary policy is activistic or not and is mostly due to the negative relationship between employment and productivity shocks when prices are relatively sluggish (Gali, 1999). A unilateral peg tends to produce the lowest level of world welfare but it sometimes represents the best monetary arrangement for the pegger. JEL Classification Numbers: E32, E52, F33, F42

Measuring Hospital Performance in the Presence of Quasi-Fixed Inputs: An Analysis of Québec Hospitals

This research proposes an approach to measure hospital performance based on a generalization of Banker and Morey (1986) and Førsund (1996). This approach considers quasi-fixed inputs explicitly, calculates their implicit cost, and quantifies returns to scale. The performance measure is decomposed into allocative and technical inefficiencies. Based on a very complete data set of Québec hospitals, we find that significant inefficiencies of up to 17% ($700 CAN million) could have been saved through improved performance. Postestimation analyses that include qualitative measures of care suggest that differences in performance are attributable to differences in management or unobservable quality of care rather than patient case mix.
