Trade Liberalisation in Developing Economies: Modest Benefits but Problems with Productivity Growth, Macro Prices, and Income Distribution

Microeconomically, the case for liberalisation is dubious under increasing returns to scale and when firms can invest directly in productivity enhancement. Distributional effects of commercial policy changes can be regressive and large, but the 'rents' they generate can serve as a basis for effective policy intervention contingent on firms' performance. Macroeconomically, the case of liberalisation rests on Say's Law, which is not always enforced. Recent combined current and capital market liberalisations have been associated with strong exchange rates and high interest rates and output and productivity growth have positive mutual feedbacks which liberalisation may well suppress.     

Complements and substitutes in sequential auctions: the case of water auctions

We use data on sequential water auctions to estimate demand when units are complements or substitutes. A sequential English auction model determines the estimating structural equations. When units are complements, one bidder wins all units by paying a high price for the first unit, thus deterring others from bidding on subsequent units. When units are substitutes, different bidders win the units with positive probability, paying prices similar in magnitude. We recover individual demand consistent with this stark pattern of outcomes and confirm it is not collusive but consistent with noncooperative behavior. Demand estimates are biased if one ignores these features.     

Asymptotics for panel quantile regression models with individual effects

This paper studies panel quantile regression models with individual fixed effects. We formally establish sufficient conditions for consistency and asymptotic normality of the quantile regression estimator when the number of individuals, n$n$, and the number of time periods, T$T$, jointly go to infinity. The estimator is shown to be consistent under similar conditions to those found in the nonlinear panel data literature. Nevertheless, due to the non-smoothness of the objective function, we had to impose a more restrictive condition on T$T$ to prove asymptotic normality than that usually found in the literature. The finite sample performance of the estimator is evaluated by Monte Carlo simulations.     

Has pharmaceutical research become more scientific?

Pharmaceutical research continues to be highly empirical, despite some recent writings arguing that it has become more scientific. Contrary to a study asserting that Mevacor, Tagamet, and Capoten demonstrate the success of targeted research, these drugs were discovered only after many years of following leads. Two hypotheses implied by the proposition that pharmaceutical research has become more scientific are tested. The first hypothesis is that the uncertainty of research has fallen. The second is that the number of publications by scientists in the industry has increased. Both are rejected.     

Enhancing Singapore travel agencies' customer loyalty: an empirical investigation of customers' behavioural intentions and zones of tolerance

The services marketing literature focuses on the measurement of service quality and its impact and consequences on businesses. Set in the context of the travel retail agency in Singapore, this study focuses on the relationship between service quality and favourable behavioural intentions. The findings revealed that improving service quality can increase favourable behavioural intentions. However, service improvements that exceed customers' minimum‐service threshold and those that exceed customers' desired‐service level were found to have mixed effect on behavioural intentions. Hence travel agencies must carefully determine the behavioural intentions they wish to foster amongst their various customers and develop service quality strategies in line with the findings of this study.
