The marked increase in the availability of spatial data has forced researchers engaged in land use modeling to directly confront the question of space and the theoretical and methodological challenges involved in developing spatial models. Advances have come from multiple disciplines, most notably through the development and application of spatial theory and methods from regional science, geography, urban economics and more recently, theoretical and applied econometrics. The main goal of this paper is to summarize the econometric challenges of spatial data and to highlight spatial models and methods with a particular focus on models of land markets and land use change. We also discuss the data and modeling challenges associated with modeling the underlying spatial economic mechanisms that give rise to land use patterns and the complexities involved in modeling land use as a coupled economic-ecological system.  相似文献

A state of the Art trend analysis of the Library and Information science reveals that the Library world is in the midst of the technological restructuring. Every branch of library work changes continuously because of the technological facilities, although the missions and goals remain unaltered. The libraries belong to these professional divisions which involve the innovation and technology transfer in everyday life. In most of the cases innovation either as a product or as a procedure goes into the libraries, it's not a phenomenon produced by them.On the strategic level libraries on average have developed the ability to collect, process and assimilate technological innovation.On the organizational level libraries follow the changes which technology transfer dictates such as close co-operation with computer centers and external commercial information suppliers, software and hardware suppliers, science and technology achievements, etc. It is too common to libraries to develop routines and Best Practices for every task, derived by the technology they use, for the cost decrease, the time save and the increase of the effectiveness and efficiency.The innovative process is the kind which libraries could adopt, as innovation is composed of the systematic retrieve of changes and systematic analysis of the opportunities which these changes could contribute to economic and social improvement.Innovation above all, is a social procedure, as it is interpreted in terms such as creativity, desires, fantasy and the ability to take risks and to change. So innovation and technology transfer differentiates the role of the librarian and extends it beyond the limits of the information intermediary. The librarian in order to involve, anticipate and especially produce innovation has to learn how to learn, as libraries have to learn how to change.The presentation will be a methodological one and will focus on Best Practices, the definition and a short report, how they combine with the library functions and how they produce innovative processes and new Best Practices. An evaluation of Best Practices according the Value Analysis method is included as a prerequisite of the final choice of which practice is characterised as Best and which not.  相似文献

The sealed-bid first-price auction of a single object in the case of independent privately-known values is the simplest auction setting and understanding it is important for understanding more complex mechanisms. But bidders bid above the risk-neutral Nash equilibrium theory prediction. The reasons for this “over bidding” remain an unsolved puzzle. Several explanations have been offered, including risk aversion, social comparisons, and learning. We present a new explanation based on regret and a model that explains not only the observed over bidding in sealed-bid first-price auctions, but also behavior in several other settings that is inconsistent with risk aversion. The authors gratefully acknowledge support from the National Science Foundation.  相似文献

Why do estimates of the intergenerational persistence in earnings vary so much for the United States? Recent research suggests that lifecycle bias may be a major factor [Grawe, N., Lifecycle bias in estimates of intergenerational earnings persistence. Labour Economics 2006, 13:551–570; Haider, S., and Solon, G., Life-cycle variation in the association between current and lifetime earnings. American Economic Review 2006, 96(4):1308–1320.]. In this paper we estimate the intergenerational correlation in lifetime earnings by using sons' and fathers' earnings at similar ages in order to account for lifecycle bias. Our estimate based on earnings measured at 35–44 for both fathers and sons is similar to that for the age range 45–54.  相似文献

The purpose of this article is to measure the efficiency of hotel units in Romania from the customers’ point of view and to identify factors that explain the differences in efficiency between hotel units. A stochastic production frontier is estimated together with a technical inefficiency model using cross-sectional data from 622 hotel units in Romania. The results show that the average efficiency is high. However, there are significant differences between hotels in different regions and with different star ratings. The most influential factor affecting efficiency is the online visibility of a hotel unit on social media platforms and on travel planning sites. The study’s results offer insight for hotel decision-makers to be able to improve the perception of hotel efficiency by taking appropriate action to meet customer needs.  相似文献

We estimate a probit model of residential land conversion using parcel-level data from a rural-urban county in Ohio. Spatial landscape pattern metrics are used to quantify land-use patterns and to link patterns of residential sprawl with factors estimated to influence parcel-level land conversion. Findings indicate that the location of new residential development is influenced by preferences for lower density areas that nonetheless are close to existing urban development. Combined, these forces have generated a moderated pattern of residential sprawl. Spatial error autocorrelation is controlled using a spatial sampling technique that enables consistent estimation of the probit model.  相似文献

In the framework of different countries' international comparison, the objective of this paper reflects research topic of investigation--the identification of small countries, revealing features of economic development and business growth in economic history context of small economies classification. The object of investigation focuses on West European and Nordic countries' small economies. The hypothesis of the article is that small states under consideration are developing as the business competitive peripheries areas due to the special Scandinavian capitalist model development characterized by high level of social capital. The statistical data base includes Organization of Economic Cooperation and Development indicators, World Bank parameters and Nordic transnational corporation's annual reports. The paper considers the following research questions: (1) the critical overview of the mainstream academicians opinions concerning different-scaled economies, (2) classification of small states and clarification of different groups of the small-scaled countries role in the world and regional economy through historical context, (3) estimates and variants of small countries' social-economic development in accordance with different parameters, (4) consideration of Nordic European countries coming to the business model of the competitive peripheral social-economic development. The main summing up conclusion is that small economies of Nordic Europe are converting nowadays into the experimental laboratory of the European and world economy due to the specific model of their social-oriented economic and business growth, their geopolitical location between developed European integration complex embracing presumably small-scaled states from one side and large-scaled emerging market economy of Asian continent from the other side.  相似文献

Ever since the setting up of the EMU, many scholars have argued that the Euro will take its place alongside the dollar and perhaps even replace it as international money. The theory behind this point of view is represented by search-theoretic models. The fundamental shortcoming of the traditional version of these models is that they fail to make a distinction between different types of money, in particular between commodity money and fiduciary money. In the international context a fiduciary money can be accepted only when a political exchange is possible between a leading country which has an interest in producing trust in the future value of its currency and other countries which attach no importance to the relative gains the issuing country acquires by exploiting the privilege of seigniorage. The Bretton Woods system and the dollar standard, although based on fiduciary monies, have worked thanks to the institutional framework maintained by the United States and accepted by other countries. Unlike the United States, the euro area is not in a position to exercise any form of political leadership on the international scene. As things stand the euro does not represent a threat to the dollar and it is bound to remain a regional money.  相似文献

We evaluate the effect of performance-based scholarship programs for post-secondary students on student time use and effort and whether these effects are different for students we hypothesize may be more or less responsive to incentives. To do so, we administered a time-use survey as part of a randomized experiment in which community college students in New York City were randomly assigned to be eligible for a performance-based scholarship or to a control group that was only eligible for the standard financial aid. This paper contributes to the literature by attempting to get inside the “black box” of how students respond to a monetary incentive to improve their educational attainment. We find that students eligible for a scholarship devoted more time to educational activities, increased the quality of effort toward and engagement with their studies, and allocated less time to leisure. Additional analyses suggest that students who were plausibly more myopic (place less weight on future benefits) were more responsive to the incentives, but we find no evidence that students who are arguably more time constrained were less responsive to the incentives.

This paper provides new empirical evidence on the effects of mergers and acquisitions (M&As) on the shape of the firm size distribution, by using data of the population of manufacturing firms in the Netherlands. Our analysis shows that M&As do not affect the size distribution when we consider the entire population of firms. When we focus on the firms involved in an M&A event, we observe a shift of the firm size distribution towards larger sizes. Firm size distribution becomes more concentrated around the mean, less skewed to the right hand side, and thinner at the tails as a whole. The shift toward higher sizes due to M&A is not uniform but affects firms of different sizes in different ways. While the number of firms in the lower tail decreased, the number of firms in the central size classes increased substantially and outweighed the increase in the number (and mean size) of firms in the upper tail of the distribution (consequently the overall market concentration measured by the Herfindahl index declines). M&As lead to a departure from log-normality of the firm size distribution, suggesting that external growth does not follow Gibrat’s law. Our counterfactual analysis highlights that only internal growth does not affect the shape of the size distribution of firms. On the contrary, it suggests that the change in the size distribution is almost entirely due to the external growth of the firms.
