This paper considers semiparametric identification of structural dynamic discrete choice models and models for dynamic treatment effects. Time to treatment and counterfactual outcomes associated with treatment times are jointly analyzed. We examine the implicit assumptions of the dynamic treatment model using the structural model as a benchmark. For the structural model we show the gains from using cross-equation restrictions connecting choices to associated measurements and outcomes. In the dynamic discrete choice model, we identify both subjective and objective outcomes, distinguishing ex post and ex ante outcomes. We show how to identify agent information sets.  相似文献

This article analyzes the origin and causes of the recent economic and financial crises, mainly for the countries located in the periphery of the European Union (EU), as well as their evolution and transformation into social, political, and institutional crises. After explaining the differential impact of the crises on EU economies, we analyze how the economic policies developed thus far not only are unable to resolve the current crisis pattern but also actually entail a risk to the present democratic models by transferring the legitimate control over governments from citizens and democratic parliaments to unelected, nonrepresentative international financial markets.  相似文献

Soybean production is one of the main economic forces driving the expansion of the agricultural frontier in the Brazilian Amazon. To assess the potential for expansion we estimate a model of soybean yield that integrates the major climatic, edaphic, and economic determinants in the Amazon Basin. Yield is modeled as a function of yield as simulated by a crop physiology model that captures the effects of climate and physical attributes on the development of soybean plant; fertilizer applications; and economic/spatial parameters such as credit, transports costs and latitude. Current values of these determinants indicate that roughly 20% of Amazon Region or ∼ 1,000,000 km2 (excluding protected areas) can generate yields greater than 2000 kg/ha. Soybean production may be possible over a wider area of Amazon, but realizing this potential requires improvements in economic determinants such as the transportation infrastructure.  相似文献

University researchers create technological opportunities that give rise to NTBF. The commercialization process of these opportunities is very complex, thus requiring universities to have programmes to support it (USOP). In this research 37 Spanish programmes, and 20 spin offs created with the support of the Technological University of Catalonia’s USOP (Innova Programme), have been examined. The study describes the technological opportunity creation, recognition and exploitation processes, and classifies the factors that determine it. Finally, the study develops a four-action-line-model that contributes to better understand how the activities carried out by USOPs minimize the barriers for spin off creation.  相似文献

Industrial statisticians frequently face problems in their practice where adjustment of a manufacturing process is necessary. In this paper, a view of the origins and recent work in the area of statistical process adjustment (SPA) is provided. A discussion of some topics open for further research is also given including new problems in semiconductor manufacturing process control. The goal of the paper is to help display the SPA field as a research area with its own identity and content, and promote further interest in its development and application in the industry.  相似文献

This paper sets out to assess the workability of the regulation currently in force in the European anchovy fishery of the VIII division. Particular attention is paid to the importance of the institutional regime in the allocation of natural resources. The study uses a bio-economic approach and takes into account the fact that, not only the European Union and the individual countries involved, but also some of the resource users or appropriators intervene in its management. In order to compare the effectiveness of the rules which, at the various levels, have been set up to restrict exploitation of the resource, the anchovy fishery is simulated in two extreme situations: open access and sole ownership. The results obtained by effective management will then be contrasted with those obtained from the maximum and zero profit objectives related with the two above-mentioned scenarios. Thus, if the real data come close to those derived from the sole ownership model it will have to be acknowledged that the rules at present in force are optimal. If, on the other hand, the situation more closely approach the results obtained from the open access model, we will endeavour in our conclusions to provide suggestions for economic policy measures that might improve the situation in the fishery.  相似文献

Exchange Rates and European Countries’ Export Prices: An Empirical Test for Asymmetries in Pricing to Market Behavior. — This paper uses forward instead of spot exchange rates to test for the presence of asymmetries in the response of export prices to exchange rate movements on a wide sample of European Union exporter countries and highly disaggregated product categories. In most cases, the data give support to the hypothesis of a symmetric pricing to market behavior during periods of depreciation and appreciation of the exporter’s currency.  相似文献

Foreign Direct Investment and Productivity Spillovers: Evidence from the Spanish Experience. — The aim of this paper is to analyse the impact of foreign direct investment (FDI) on firms’ productivity using a panel of Spanish manufacturing firms for the period 1990–1998. Firstly, we show that for countries, like Spain, that are undergoing significant structural changes over the period in question it is important to control for both time-invariant as well as time-variant sectoral characteristics. Secondly, we confirm previous findings that one needs to take into account the “absorptive capacity” of firms when considering whether they are able to avail of externalities associated with FDI presence. For the Spanish case we find that only firms with sufficient levels of such capacity experience positive spillovers.  相似文献
