Technical Progress and Product Reliability under Competition and Monopoly

Technical progress lowers costs and prices but appears to have an ambiguous effect on product reliability. This paper presents a simple model which explains this observation. Copyright © 2013 John Wiley & Sons, Ltd.     

The political economy of tariff protection in China: evidence from the WTO accession

We analyze China's tariff rates at WTO accession using a political economy approach. A model drawing on Branstetter and Feenstra ( 2002 ) is used to derive an optimal tariff rate for each industry. The model predicts that a government would set a high tariff rate if an industry is of large state‐owned enterprise (SOE) share, multinational share, or small foreign import share. From the model we reveal the Chinese government's preference towards different interest groups under the binding tariff constraint from the WTO commitments. The estimated structural parameters imply that the political weights on both the SOE profits and consumer income diminish with the economic opening. More important, the government still favours SOEs over consumer income. Our findings are consistent with the special features of China's economy.     

Trade liberalization,wages, and specialization in China

This paper studies the evolution of regional specialization in China in response to trade liberalization. Using a panel of Chinese export data at the detailed commodity level over the period of 1988–2006, we show that China’s regional specialization follows a U-shaped pattern: both the interior and coastal regions diversify from 1988 to 1994 but specialize during the later reform period of 1994–2006. A theory of tariff reductions is proposed by constructing the Dornbusch–Fischer–Samuelson (1977) continuum of goods Ricardian model in a setup of two countries and three regions. The U-shaped pattern of specialization can be obtained from foreign tariff reductions followed by Chinese tariff reductions. This finding is supported by simulations, US–China trade policy review, and the pattern of China’s coast–inland wage ratio.     

Panel asymmetric nonlinear unit root test and PPP in Africa

This study revisits purchasing power parity (PPP) theory for 20 African countries using panel asymmetric nonlinear unit root test proposed by Emirmahmutoglu and Omay (2014), through the sequential panel selection method of Chortareas and Kapetanios (2009). While standard panel unit root tests fail to support the PPP, the empirical results from panel asymmetric nonlinear unit root test do support the PPP. However, additional tests reveal that support in all 20 African countries is mostly due to stationarity of the real effective exchange rates of Ghana and Rwanda where the adjustment process towards equilibrium is nonlinear and asymmetric.     

非标准工作与体面劳动:数据化带来的劳动问题与政府对策

数据化促进了经济发展,也造成了传统雇佣模式的变化.本文以互联网平台为例,从国际视角分析了数据化带来的劳动者权益保障问题,并简要概括了国际劳工组织与发达国家解决这些问题的对策.笔者提出,互联网平台从业者大部分从事的是非标准工作,这类工作存在体面劳动方面的诸多缺陷.笔者认为,在传统雇佣关系发生变化之后,无需再用传统的定义和标准去研讨非标准工作从业者是否具有“雇员”的身份,而应当将这些通过劳动获得报酬的从业者视为“劳动者”.笔者指出,政府应当尽其所能,制定和修改劳动政策,为他们提供底线型的基本保障,帮助他们实现体面劳动.     

Regulatory arbitrage and the FERC rate settlement process

We demonstrate that the Federal Energy Regulatory Commission’s (FERC) regulatory procedures for natural gas pipelines, specifically its rate-refund policy, induces regulatory arbitrage that leads to economic distortions. Specifically, we demonstrate that the rate refund policy causes pipelines effectively to “extort” ratepayers through the addition of economically inefficient capital investment, akin to “gold-plating” investments. We estimate the potential magnitude of this arbitrage impact on ratepayers to be between $400 and $700 million annually. Counterintuitively, however, we demonstrate that the presence of this arbitrage opportunity leads to underinvestment in pipeline capacity, thus negating one of the principal purposes of rate regulation. We further demonstrate that FERC could easily eliminate this regulatory arbitrage by setting the refund interest rate to the pipeline’s as-filed weighted average cost of capital.     

The Role of Customer Factors in Multiple Store Patronage: A Cost-Benefit Approach

This paper is concerned with the use of multiple stores by supermarket customers. It relates the number of stores patronized to a set of customer factors under a unifying theoretical framework emphasizing cost-benefit analysis. Respective hypotheses are tested in a large random sample. This study is a first attempt to empirically address the structure of multiple store patronage. It is demonstrated that multiple store patronage is affected by variables such as customer income, satisfaction, and expenditure that are suggestive of heterogeneous cost-benefit tradeoffs and opportunity costs of time. It is shown that customers are intrinsically different in the predisposition to being loyal. In this respect, store patronage is a continuum between single store loyalty and use of several different stores, on which customers vary depending on individual preferences. The empirical analysis also suggests that exclusive patronage of the favorite store arises from two observationally equivalent latent segments that differ in their inclination to remain loyal. The results yield valuable insights into the structure of store patronage and lead to important implications for retail managers. Several extensions are considered. A broad set of research questions surrounding store patronage can be considered from a cost-benefit viewpoint in the sense that consumer decisions in this area involve trading off economic resources against assortment, spatial and temporal benefits.     

Comparative advantage and unemployment

Worker heterogeneity in productivity and labor supply is introduced into a matching model. Workers who earn high wages and work high-hours are identified as those with strong market comparative advantage—high rents from being employed. The model is calibrated to match separation, job finding, and employment in the SIPP data. The model predicts a big drop in employment for workers with weak comparative advantage during recessions. But the data show that workers with strong comparative advantage also display sizable employment fluctuations, implying that aggregate employment fluctuations are not explained by the responses of workers with small rents to employment.     

Innovation, rule breaking and the ethics of entrepreneurship

This article examines a feature of the ethics of entrepreneurship that is infrequently directly discussed, viz., rule breaking. Entrepreneurs are widely said to engage in rule breaking. Many examples of this appear in popular and academic literature. But how may this be integrated into an account of the ethics of entrepreneurship? One response would be that when entrepreneurs break legal and moral rules then what they do is wrong and ought to be condemned. There is a great deal to be said for this rule model of entrepreneurial ethics. However, this view is also mistaken. Instead, this article defends a virtue-based account of the ethics of entrepreneurship in which certain instances of rule breaking, even if morally wrong, are nevertheless ethically acceptable and part of the creative destruction that entrepreneurs bring not only to the economy but also to morality.
