Using Turkish industry-level data from 1983 to 1990, we find that politically organized industries receive both higher protection and promotion than unorganized ones. Tariff rates are decreasing (increasing) in the import-penetration ratio and the absolute value of the import-demandelasticity for organized (unorganized) industries. Subsidy rates are decreasing (increasing) in the output-supply elasticity for organized (unorganized) industries. The results are consistent with the predictions of the Grossman–Helpman model and its extension in this paper. The mix of protection and promotion is inversely related to the ratio of their respective marginal deadweight cost measures.  相似文献

Cross‐docking replaces traditional warehousing, enabling continuous flow of items without storage. Here we model location‐distribution networks, that include cross‐docking facilities, to obtain the latter's impact on the supply chain. We formulate optimization models to minimize total cost in three multi‐echelon networks, each model generalizing the preceding one. The first includes a single manufacturer, one product type, and multiple customers. Cross‐docks are to be located between origin and destinations. Besides solving optimally, a tool for quantitative analysis of direct‐shipment decisions is developed. The second model considers more than one product: We determine a cost‐effective sequence of items for indirect shipment (via cross‐docks). Finally, in a network with multiple origins, optimal solutions are obtained for 40 medium‐sized and larger examples.  相似文献

Comovement of stock market indices increases during volatile periods, and does not come down when the turmoil settles down. This paper explains formation of persistent comovements during high volatility periods with theories from Bayesian learning. My main conclusion is that the correlation that is formed during the high volatility period is persistent because it is learned during the turmoil. The belief that interdependence between markets are high during the volatile period turns into reality by correlated actions of traders in different markets avoiding correlation to fall to its previous level.  相似文献

Scenarios of Japanese society in 2000 are obtained by applying an extended correlational cross impact analysis. Since the scope of the scenarios is extensive, a procedure is developed to generate the scenarios that consists of a preprocessing of the events of interest and a step-by-step application of a cross impact method. Three scenarios are described, based on a workshop where the procedure was applied.  相似文献

The European Union (EU) aspires to be the most competitive, full employment economy in the world and has set a number of ambitious targets to be met by 2010 in order that it can achieve this goal. At the same time, it is pursuing an enlargement policy that will witness the accession of an increasing number of less developed nations. This article explores some of the tensions that exist between these two goals as these are manifest in labour market indicators and finds the likelihood of meeting the deadline set for success remote.  相似文献

This paper tests whether housing prices in the five segments of the South African housing market, namely large-middle, medium-middle, small-middle, luxury and affordable, exhibit non-linearity based on smooth transition autoregressive (STAR) models estimated using quarterly data from 1970:Q2 to 2009:Q3. Findings point to an overwhelming evidence of non-linearity in these five segments based on in-sample evaluation of the linear and non-linear models. We next provide further support for non-linearity by comparing one- to four-quarters-ahead out-of-sample forecasts of the non-linear time series model with those of the classical and Bayesian versions of the linear autoregressive (AR) models for each of these segments, for the out-of-sample horizon 2001:Q1 to 2009:Q3, using the in-sample period 1970:Q2 to 2000:Q4. Our results indicate that barring the one-, two and four-step(s)-ahead forecasts of the small segment, the non-linear model always outperforms the linear models. In addition, given the existence of strong causal relationship amongst the house prices of the five segments, the multivariate versions of the linear (classical and Bayesian) and STAR (MSTAR) models were also estimated. The MSTAR always outperformed the best performing univariate and multivariate linear models. Thus, our results highlight the importance of accounting for non-linearity, as well as the possible interrelationship amongst the variables under consideration, especially for forecasting.  相似文献

Culture plays an increasingly important role in supply chain management as many manufacturing firms have linkages to suppliers and customers from various countries. In this paper we propose treating culture as an explanatory variable to test the assumption that existing theories are universally applicable. The primary research question was: Do purchasing theories built on samples from mainly North American companies with Anglo-Saxon cultures apply in other cultural contexts? We developed and tested a model where top management??s view of the purchasing function affects purchasing practices and manufacturing performance. The statistical results provide evidence that the engagement and efficacy of purchasing practices is highly dependent on culture. This finding has significant implications from the perspective of decision making in international supply chain management. Specifically, top managers across multiple cultures could decide to structure and evaluate the purchasing function similarly, but these decisions could lead to different practices and different outcomes depending on the culture.  相似文献

This paper presents the reasons for uncontrolled land-use changes in the water resource basins of Istanbul. These changes are evaluated with a Geographical Information System (GIS), using four Landsat (1990, 1995, 2000, 2005) satellite images. Additional spatial information about capital improvement projects (highways and the Bosporus bridges), industrial land-use decisions, land ownership, and jurisdictional boundaries is also utilized. We observe that the most critical land-use changes have occurred in places with higher accessibility, mostly in close proximity to the metropolitan city center. The literature describes large public capital improvement projects (primarily the Trans European Motorway – TEM) as the primary reason for a trend of illegal occupation of public lands; however, the TEM should not be considered as the sole reason. This study explores other possible causes for these illegal developments in the water resource basins, grouped into three broad dimensions physical, socio–economic–political, and legal. Finally, we put forward possible policy suggestions for the preservation of the limited surface water resource basins in Istanbul.  相似文献
