We provide empirical evidence on the determinants of income inequality in Bosnia and Herzegovina after the civil war. To do this, we use a an ordered probit approach and take advantage of the first post‐war household survey for the country which sheds some light on the influence of regional differences as well as household characteristics on income quintile determination. With respect to the former, we find large income differences between the two entities in the country, the Federation and Republika Srpska. Such income differences are also noticeable inside entities. On the latter, there are some signs that education, experience, and employment, among others, may help reduce the probability of income decline. Our results are robust to changes of specification as shown by applying a formal sensitivity analysis. JEL classification: O15, O10, I30. 相似文献

This paper addresses income distribution issues and policy options to eliminate extreme poverty in a particular typology of middle-income semi-industrialized developing countries of Latin America. The countries included in the typology are characterized by a relatively high per capita income (above US$700/yr in 1977), a relatively high degree of industrialization (industry representing over 30% of GNP), a rather large size both in population and area, and relatively well endowed resources in agriculture. A distinctive feature is a strong inequality in the distribution of income and wealth relative to other countries of similar levels of per capita income. The countries included are Brazil, Columbia, Ecuador, Mexico and Peru, representing two-thirds of the population of that region. 相似文献

The mobile telephony sector is characterized by the dynamic interplay of rapid changes in technology and an apparently growing competition, as indicated by the fierce nonprice competition, and is yet associated with the entry of new operating companies in some cases. In this context, a relevant and neglected issue is the assessment of how service quality responded to an increasingly competitive environment. This study utilizes data envelopment analysis to assess the quality efficiency of mobile telephony companies in Brazil during the 2000–2003 period. Window analysis was conducted for the entire period, taking as reference different quality indicators pertaining to different forms of complaints and calls completed and interrupted. The efficiency measurement was made feasible by interpreting the indicators reflecting a positive dimension of quality as outputs and those reflecting negative aspects of quality as inputs. Given potential heterogeneities across firms that relate to the frequency band and to the technology (time division multiple access technology and code division multiple access technology among others), this article considered adjusted efficiency scores. The Tobit model for censored data was estimated to control for the aforementioned aspects. Rescaled residuals from the econometric estimation produced efficiency scores for service quality. The evidence indicated an overall improvement in efficiency over time. Nonparametric tests were consistent with a positive evolution of quality over time even for shorter subperiods. 相似文献

Increasingly, innovation is conceived in a context of conventions or rules and complexity. However, there is a need for a theoretical basis that describes the innovation process based on complexity. In this essay, we propose a multilevel micro-meso-macro framework that aims to meet this need and further the discussion on complexity. In this framework, the rule is adopted as an analytical concept and used to establish a bridge between the several theories employed. Two gaps are identified in the innovation process: the first is related to the simplicity with which complexity is generally treated, and the second refers to a lack of focus on the rules embedded in the theories used in innovation. The goal of this theoretical essay is to propose a multilevel micro-meso-macro framework, based on the rules and principles of complexity, which can be used to analyze the innovation process. As a result, we propose a new framework in which the innovation rules and the interactions between those rules are detailed and based on principles of complexity. 相似文献

A key element in evaluating fishery management strategies is examining their effects on the economic performance of fishery
participants, yet nearly all empirical studies of fisheries focus exclusively on the amount of fish harvested. The economic
benefits derived from fish stocks involve the amount of revenue generated from fish processing, which is linked to both the
way fish are harvested and the products produced from the fish. In this study we econometrically estimate a flexible revenue
function for catcher-processor vessels operating in the Alaskan pollock fishery, recognizing potential endogeneity and a variety
of fishing inputs and conditions. We find significant own-price supply responses and product substitutability, and enhanced
revenues from increased fishing days and tow duration after a regulatory change introduced property rights through a new fishing
cooperative. We also find significant growth in economic productivity, or higher revenues over time after controlling for
observed productive factors and price changes, which exceeds that attributable to increased harvest. These patterns suggest
that the move to rights-based management has contributed significantly to economic performance in the pollock fishery. 相似文献

We study the TFP distribution and examine the non-stationarity of productivity series at various quantiles. Using the quantile autoregression unit root test, we find that the US TFP exhibits an asymmetric adjustment dynamics, that is, positive and negative shocks might have different (permanent or temporary) effects on the TFP. Shocks dissemination depends on the local behaviour of the TFP. We find that positive shocks have permanent effects on the TFP, while negative shocks can potentially have only transitory effects. 相似文献

The literature on monetary economy has aroused growing interest in macroeconomics. Due to computational advancements, models have become increasingly more complex and accurate, allowing for an in-depth analysis of the relationships between real economic variables and nominal variables. Therefore, using a dynamic stochastic general equilibrium (DSGE) model, based on Gali and Monacelli (2005), we propose and estimate a model for the Brazilian economy by employing Bayesian methods so as to assess whether the Central Bank of Brazil takes exchange rate fluctuations into account in the conduct of monetary policy. The most striking result of the present study is that the Central Bank of Brazil does not directly change the interest rate path due to exchange rate movements. A simulation exercise is also used. Our conclusion is that the economy quickly accommodates shocks induced separately on the exchange rate, on the terms of trade, interest rate, and global inflation. 相似文献

Indirect assessments of market conduct have become widespread in the New Empirical Industrial Organization—NEIO literature.
Recently, Steen and Salvanes (1999, Int J Ind Organ 17:147–177) provided a flexible dynamic econometric formulation of the
approach advanced by Bresnahan (1982, Econ Lett 19:87–92) and Lau (1982, Econ Lett 10:93–99). The present paper considers
a similar approach applied to regional cement markets in Brazil under more favorable data availability, and attempts to address
part of the concerns that usually emerge with respect to the NEIO literature. In particular, issues pertaining to structural
stability and the control for the number of competing firms are addressed. The evidence clearly indicates non-negligible and
distinct market power in different regions and also distinct conduct patterns in the short and long run.

The United States grants preferential (tariff‐ and quota‐free) market access to a list of products from eligible countries in sub‐Saharan Africa through the African Growth and Opportunity Act (AGOA). We analyse the increase in prices received by apparel exporters who benefited from AGOA preferences. In the presence of competitive markets, export prices should increase as much as the tariff which was previously collected by the US government. We refer to this price increase as the ‘tariff preference rent’ since exporters receive this income as the rent for their preferential status. The results show that exporters receive only one‐third of this rent and smaller exporters receive less than larger and established ones. We then provide evidence that suggests this may be due to the degree of market power enjoyed by US importers when facing African exporters. 相似文献

The objective of this paper is to evaluate the relative importance of three distinct factors that motivate redistributive government policy: tariff revenues, consumer welfare, and producer profits. We generalize Grossman and Helpman's (1994, American Economic Review 84: 833–850). protection‐for‐sale model by positing that government places different weights on these components of the welfare of its polity when it decides which industries to protect and to what extent. Employing tariff data from 40 countries, the predictions from this model are used to estimate these weights. The results are surprising in their range and variety. Developing countries with weak tax systems often weigh tariff revenue heavily, while more developed countries weigh producer interests the most. Very few hold consumer welfare dear. 相似文献
