The development of information and communications technology (ICT), particularly the Internet, has reduced trade costs. However, it remains unclear whether these reduced costs are reflected in the “extensive margins” of firms’ exports (which refer to the probability of firms exporting) or the “intensive margins” (which refer to the value of firms’ export). To test this, we used the concepts of information cost and binary margins, an augmented trade model of firm heterogeneity, a two‐stage Heckman estimation, and data from the World Bank Enterprise Survey of Chinese firms in 2012. The results revealed that reduced trade costs from the use of ICT were positively related to extensive margins but that the connection with intensive margins was not significant. The results lead to the conclusion that reduced information costs related to a firm's exporting behavior were primarily reflected in variable trade costs. This study offers theoretical and empirical evidence for China's policies towards the Internet, which are relevant for the export of manufactured goods. The government should encourage the use of ICT to enhance firms’ export opportunities while facing current trade policy uncertainty. 相似文献

A strand of the literature documents no effects or even positive effects of a higher minimum wage on employment. This evidence is frequently linked to the existence of monopsonistic labor markets or search frictions. However, empirical studies show that these findings could be related to a low short‐term minimum wage–employment elasticity in a competitive labor market. We show that mixed theoretical employment effects of a minimum wage policy can be predicted in the short term in assignment economies with price‐taker agents and no search frictions. 相似文献

This article develops a model of three faces of labor from Figart, Mutari, and Power’s three faces of wages. This is integrated with sustainability models to locate the process of human and social capital formation and explore issues arising from technological change. The latest wave of automation, involving robotics and artificial intelligence, is expected to be an even greater challenge for worker well-being than globalization and immigration. The model supports a new narrative around labor that incorporates the caring economy as well as a framework for thinking about labor issues and long-term well-being. 相似文献

ABSTRACT In a posthumously published article, Pierangelo Garegnani (2018. ‘On the Labour Theory of Value in Marx and in the Marxist Tradition.’) depicts Marx’s project in Capital as that of ‘developing systematically the theory of Ricardo and [the] implications of social conflict’ implied by Ricardo’s ‘surplus approach to value and distribution’. This paper argues to the contrary that Marx’s theory of surplus value and exploitation differs from (neo-)Ricardian surplus theory in fundamental ways, and modifies Garegnani’s simple Sraffian model to illustrate the distinctive implications of Marx’s theory. 相似文献

We study the factors influencing the percentage of organic and fair trade certified coffee sold through a cooperative by growers of five cooperatives in Mexico. The percentage of coffee sold through the cooperative was used as a proxy of growers’ engagement with a cooperative. Using factor analysis and a fractional probit regression, we evaluated the proposition that the level of engagement can be explained by transaction cost economics, social norms and connections, and farmer and farm business characteristics. We found that farm size, uncertainty regarding cooperative time of payment to the members and cooperative commitment on price to be paid negatively influence the level of engagement. In contrast, asset specificity, relational commitment, and price have a positive impact on engagement. Our results may help cooperatives and policy makers to build strategies aiming to increase this level of engagement. This is relevant because lower grower engagement has been found to be positively correlated with weak performing cooperatives. 相似文献

Cost‐reflective pricing: empirical insights into irrigators’ preferences for water tariffs 下载免费PDF全文
Bethany Cooper Lin Crase John M. Rose 《The Australian journal of agricultural and resource economics》2018,62(2):256-278
Using prices to improve the efficiency with which water resources are allocated is now widely accepted in principle if somewhat difficult to achieve in practice. Whilst there are some technical difficulties associated with full‐cost recovery in irrigation, the lack of political will to tackle reform remains a significant impediment. This article reports the results of an empirical investigation into farmers’ preferences for changes to water prices and tariff structures. We conclude that some of the preferences of farmers are conducive to price reform. We also find evidence that public subsidy of infrastructure in irrigation is not always aligned with the preferences of farmers. 相似文献

ABSTRACTIn this study, we investigated whether the exchange rate and the interest rate had an effect on the inflation rate in the fragile five countries between the years of 1996Q4 and 2015Q4. In this context, a model was created to estimate the effect of interest rate and exchange rate on the inflation rate. The methods used in the study take into account cross-section dependence and heterogeneity. As a result of the analysis, it was determined that there was an exchange-rate and interest-rate pass-through effect in the fragile five countries. Moreover, it was found out that the cost channel and price puzzle were effective in Indonesia and South Africa but were not effective in Turkey, Brasil and India. 相似文献

Abstract:This article uses a simple economic model to study important issues in debates about distributive justice. What role do non-labor productive assets play? What role does private ownership play? What role does scarcity play? What role do credit and labor markets play? The model is used to address these questions, and in the process explain why even if those who acquire scarce productive assets do so fairly, and in a manner that deserves compensation, there is reason to believe (1) that when people own productive assets privately outcomes will become unfair, and (2) credit and labor markets will aggravate inequities. The article concludes that distributive justice requires compensation commensurate with the economic sacrifices people make and acknowledges important challenges that must be overcome to achieve this. 相似文献
