This paper examines the microeconomic determinants of residential real estate prices in Caracas, Venezuela, using a private database containing 17,526 transactions from 2008 to 2009. The particular institutional characteristics of many countries in Latin America, and Venezuela in particular, where land invasions and expropriations (with only partial compensation) have been common threats to property owners, provide us with an opportunity to test the effects of these risks on housing prices using a unique database. The effect of these risks on property prices is negative and significant. To our knowledge, this is the first attempt to quantify these impacts in the Hedonic pricing literature applied to real estate. Size, the number of parking spaces, the age of the property, the incidence of crime, and the average income in the neighborhood are significant determinants of prices. Finally, this paper analyzes the microeconomic determinants of housing prices at the municipal level. 相似文献

This paper explores the consequences of nonlinear wealth dynamics for the formation of bilateral credit arrangements to help manage idiosyncratic risk. Using original data on expected wealth dynamics, social networks and informal loans among southern Ethiopian pastoralist households, we find that the threshold at which expected wealth dynamics bifurcate serves as a focal point at which lending is concentrated. Informal lending responds to recipients' losses but only so long as the recipients are not “too poor”. Our results suggest that when shocks can have long term effects, loans are best understood as providing a safety net rather than a scale-neutral insurance mechanism. Furthermore, the persistently poor are excluded from social networks that are necessary to obtain loans given in response to shocks. 相似文献

Further simulation evidence on the performance of the Poisson pseudo-maximum likelihood estimator 总被引:3,自引:0,他引:3
We extend the simulation results in Santos Silva and Tenreyro (2006, The log of gravity, The Review of Economics and Statistics, 88, 641-658) by considering a novel data-generating process. Our results confirm that the Poisson pseudo-maximum likelihood estimator is generally well behaved, even when the proportion of zeros in the sample is very large. 相似文献

This study investigates the major factors that can influence electronic data interchange (EDI) within the hotel industry. Results illustrate that some profile, channel, and task variables can influence EDI usage in the areas of purchasing, financing, and strategy. By identifying and testing relevant intraorganizational variables, this study offers insights to academics and practitioners regarding the usage of EDI within the hotel industry. Indications are EDI could become an important tool for hotels to use in conducting business in both an interorganizational and intraorganizational manner. 相似文献

Tourism firms are increasingly integrated in value chains that often operate across many different countries. As a result, the concepts and the methodology of the global value chains begin to be applied to the tourism industry. This paper aims to explore the applicability of this methodological approach for a specific service industry, such as tourism. It pays particular attention to the impact of different patterns of governance within global tourism value chains on the possible forms of upgrading. First, a set of regional case studies carried out on this subject leads us to identify the main patterns of governance in the Andalusian tourism industry. Secondly, an empirical analysis allows us to consider in which way upgrading can vary according to the governance patterns. 相似文献

An implication of two-country international real business cycle models is that total factor productivity should be an exogenous stochastic process. Economic theories which feature labor hoarding, variable capacity utilization, and increasing returns predict that measured productivity shifts are not exogenous; instead, expansionary aggregate demand shocks should lead to an increase in measured productivity. For each of the G-7 countries, this paper measures quarterly aggregate total factor productivity for the domestic country and its rest-of-world (G-6) counterpart. In each case the domestic productivity measures are not strictly exogenous: expansionary U.S. monetary policy shocks, as well as other G-6 monetary policy shocks, lead to productivity expansions. The evidence indicates that international business cycle models are misspecified unless they feature endogenous productivity mechanisms.Received: June 2001, Accepted: December 2001, JEL Classification:

Summary. This paper studies the pricing of money in an infinite-horizon economy with heterogeneous agents, incomplete financial markets and arbitrary borrowing restrictions. Purchases of the consumption good are subject to a cash-in-advance constraint. Under general conditions I show that the price of money is equal to its fundamental value, where this value is defined over all state-price processes that are compatible with the existence of no-arbitrage opportunities. This equality implies that the cash-in-advance constraint is binding infinitely often for all agents in the economy. The analysis highlights certain differences in the determination of the price of money with respect to models with money in the utility function that bear on the optimal implementation of economic policies.Received: 23 October 2003, Revised: 26 August 2004 JEL Classification Numbers:

We examine the higher order properties of the wild bootstrap (Wu, 1986) in a linear regression model with stochastic regressors. We find that the ability of the wild bootstrap to provide a higher order refinement is contingent upon whether the errors are mean independent of the regressors or merely uncorrelated with them. In the latter case, the wild bootstrap may fail to match some of the terms in an Edgeworth expansion of the full sample test statistic. Nonetheless, we show that the wild bootstrap still has a lower maximal asymptotic risk as an estimator of the true distribution than a normal approximation, in shrinking neighborhoods of properly specified models. To assess the practical implications of this result we conduct a Monte Carlo study contrasting the performance of the wild bootstrap with a normal approximation and the traditional nonparametric bootstrap. 相似文献

Supply chain risk management (SCRM) has become a popular topic over the past decade. It is not a surprise that the automotive industry has been a motivating arena for research within this field; however, the few existing empirical studies reveal that SCRM practices within this industry are still in their infancy. Because the identification of risks can be viewed as the trigger for SCRM, attempts to develop a risk profile for this industry that could serve as a guide to start the SCRM process are needed. This research identifies the main risks along the automotive supply chain by investigating their manifestation in three supply chains in Brazil and offers an initial risk profile for the Brazilian automotive industry. Although the importance of SCRM has been recognised by all analysed companies, the research findings underline the lack of preparedness regarding either identifying risk or considering risk-mitigation strategies and risk assessment. In this context, this study identifies the main risk in which a supply chain can be exposed, through the analysis of real-life manifested risks along different supply chains, as a way to help the supply chain start a SCRM process. 相似文献
