This article empirically analyses how households’ PC purchasing behaviours change with market experience. We find that: households generally exhibit inertia in their PC purchases, the level of inertia is increasing as a function of experience on the PC market, and, for households switching brands, the likelihood of buying a lesser-known brand increases with experience, regardless of the brand of the previous purchase. These findings are consistent with the predictions of a simple learning model, and extend our understanding of how market experience affects purchasing behaviour to an important technology product, with implications that may apply to other similar products.  相似文献

This analysis examines the demand for a system of regional parks in Sicily (Italy). The analysis utilizes conventional count data methods that do not account for correlation across parks as well as a new model that allows for cross-site correlation and dispersion. In this model, the degree of dispersion and cross-site correlation is shown to evolve as individual grow older. Older individuals exhibit less dispersion and/or cross-site correlation.  相似文献

This article uses a new database to establish a key finding: high tariffs were associated with fast growth before World War II, while they have been associated with slow growth thereafter. The paper offers explanations for the sign switch by controlling for novel measures of the changing world economic environment. Rejecting alternative explanations based on changing export market growth or transportation cost declines, it shows how the modern negative correlation could be reversed in a world environment characterized by a moderately higher generalized tariff protection such as that which prevailed before 1914. We show that an increase in average tariff rates among trading partners by just one third might suffice to reverse any negative relationship between an average country's tariffs and its growth. An increase in own tariffs after 1950 hurt or at least didn't help growth, but it might have helped growth in a world where average trading partners' tariffs were moderately higher and retaliation was the best strategy. The world environment matters. Leader-country reaction to big world events matters.  相似文献

A large part of the literature on provincial inequality in China has found it necessary to include regional dummies in the provincial growth regressions. A smaller but vocal part of the literature has emphasised the granting of preferential policies to explain the faster growth of the coastal provinces. We replace the regional dummies with a measure of the ability to participate in international trade (Geography), and a preferential policy index (Policy). We find that geography and policy had about equal influence on coastal growth (3 percentage points each). Geography affected growth with a much longer lag than policy, however. The policy index was highest for the metropolises (Beijing, Shanghai, and Tianjin) and lowest for the central and northwestern provinces. The preferential policies are to a large extent “deregulation policies” that enabled marketization and internationalization of the coastal economies and allowed them to become more like their East Asian neighbours (and competitors). The weak (statistically insignificant) support for conditional convergence is in line with the existence of institutions that retard the income convergence process generated by the movement of labor and capital and by the Stolper–Samuelson mechanism. The household registration system ties the peasants to the land, the monopoly state bank system favors borrowing by state enterprises, and local protectionism reduces inter-provincial trade. Clearly, these institutions need to be deregulated. An effective strategy to develop the western provinces must therefore encompass physical capital formation, human capital formation, and institutional capital formation.  相似文献

An exactly aggregable system of Gorman Engel curves for US food consumption is developed and implemented. Box-Cox transformations on prices and income nest functional form. The model nests rank up to rank three. The model is estimated by nonlinear three-stage least squares with annual time series data on 21 foods, 17 nutrients, age and race demographics, and the distribution of income for 1919–1941 and 1947–2000. Results are consistent with full rank three. Point estimates for the Box-Cox parameters on income and prices are 0.86 and 1.09, respectively, strongly rejecting zero and one in both cases. No statistical evidence of serial correlation, specification errors, or parameter instability is found.  相似文献

This study investigates the use of hedonic pricing to identify the value of relevant production and type traits for dairy bulls in Alberta. A hedonic pricing model is estimated that considers semen price as a function of individual production and longevily characteristics for a sample of Holstein bulls. The results suggest that the most important characteristics used by Alberta daity producers in valuing dairy bulls are milk volume, protein and fat content, general conformation, body capacity and the popularity of the bull. For a given set of such characteristics, the probability that the bull's semen may be in short supply does not significantly affect the value. This methodology may be used to establish a method of forecasting semen prices for newly proven bulls. The valuation procedure may be easily updated and adjusted as producers'breeding objectives change over time because of the changing economic environment. The results of this analysis suggest that hedonic pricing may be a better method of placing a value on production and type characteristics for dairy bulls than the Lifetime Profit Index currently being used by the Canadian dairy industry.  相似文献

Summary.  We investigate, in an experimental setting, the behavior of single decision makers who at discrete time intervals over an “infinite” horizon may choose one action from a set of possible actions where this set is constant over time, i.e. a bandit problem. Two bandit environments are examined, one in which the predicted behavior should always be myopic (the two-armed bandit) and the other in which the predicted behavior should never be myopic (the one-armed bandit). We also investigate the comparative static predictions as the underlying parameters of the bandit environments are changed. The aggregate results show that the behavior in the two bandit environments are quantitatively different and in the direction of the theoretical predictions.

Previous closed‐end country fund research concludes that returns behave more like the U.S. market than like their target markets. We argue this finding may be biased by model misspecification and inappropriate estimation techniques. We propose a single‐equation model containing five hypothesized factors of fund returns. We estimate this model for nineteen pooled seasoned funds using a time‐series cross‐section regression that corrects for two types of autocorrelation. We show that returns are strongly related to target markets. Returns are also related to changes in discounts, exchange rates, and other countries' markets, but are only weakly related to the U.S. market. JEL classification: G10, G12  相似文献
