Exclusive Contracts And Market Power: Evidence From Ocean Shipping

There is a substantial theoretical literature on the potential effects of loyalty contracts, but relatively little empirical work. We employ the event study methodology to examine the competitive effects of exclusionary contracts in the ocean shipping industry, where they were the subject of an extended legal and political struggle. We find that some of the most important events in this conflict caused significant changes in shipping firms' stock returns, indicating exclusive contracts increased their profits. We then examine the effect of these events on net exporting industries' stock returns, and provide evidence that these contracts contributed to carriers' market power.     

Influences on software piracy: Evidence from the various United States

Examining socio-economic influences on software piracy in the United States, we find a negative relationship between software piracy and income, tax burdens, and economic freedom. A 1% increase in per-capita income correlates with a 0.25% reduction in piracy.     

Does Ethnic Discrimination Vary Across Minority Groups? Evidence from a Field Experiment*

We conduct a large‐scale field experiment to measure labour market discrimination in Australia, one quarter of whose population was born overseas. To denote ethnicity, we use distinctively Anglo‐Saxon, Indigenous, Italian, Chinese and Middle Eastern names. We compare multiple ethnic groups, rather than a single minority as in most other studies. In all cases we applied for entry‐level jobs and submitted a CV indicating that the candidate attended high school in Australia. We find significant differences in callback rates: ethnic minority candidates would need to apply for more jobs in order to receive the same number of interviews. These differences vary systematically across ethnic groups.     

Strategy in research design and hypothesis testing

The efficiency of a research design may be measured in terms of the degree to which knowledge is enhanced within given resource constraints. Thus, two different types of research design, even though they contain the same number of expected observations, may differ considerably in the amount of information provided. An example is the number N of 32 observations obtained with an analysis of variance witheither 2 factors, 2 levels per factor and a replication of 8or 4 factors, 4 levels per factor and a replication of 2. We analyze and compare the relative efficiencies of regression and variance analysis models and their implications to research strategy development. Three major considerations are evaluated: (1) short versus long time horizon (interval until effects of a decision are realized), (2) small versus large cost of erroneous rejection of the Null Hypothesis and (3) gross versus refined stage of development of the research study. A set of general guidelines towards improved designs is developed.     

从"双缺口"到"双溢出"——我国引进外资的现状与对策分析

改革开放初期,由于缺乏建设资金,我国用各种优惠政策吸引外资以加快经济建设,取得了显著成效.但近些年来,在利用外资促进经济发展的过程中,外资流入与国内储蓄"双溢出"现象日益突出,这似乎与传统的利用外资"双缺口"理论相悖,但实际情况并非如此.本文分析论述了我国引进外资从"双缺口"到"双溢出"的变化过程及原因,并论述了在"双溢出"情况下应该如何引进外资.     

On a 2 × 2 factorial design where the use of randomized response is one of the factors

This paper discusses a survey where some respondents were asked sensitive questions directly and others were asked the same questions using randomized response. The use of randomized response was a factor in a 2 × 2 factorial design and dice were used to perform the randomization. First, the paper shows that the perturbation due to the dice can be described using the concept of misclassification and known conditional misclassification probabilities. Second, the paper formulates the likelihood for loglinear models and shows that latent class software can be used to analyse the data. An example including a power analysis is discussed.     

Are the choices of people stochastically rational? A stochastic test of the number of revealed preference violations

Revealed preference tests are frequently used to check data on the behavior of agents for consistency with economic theory. Unfortunately these tests lack a stochastic element and thus one violation of revealed preference causes a rejection of the behavior being tested. To remedy this lack of a stochastic element in revealed preference analysis, we suggest a general, simple, and intuitive statistical procedure to test whether the observed number of violations is more consistent with a pre-specified type of non-degenerate behavior than with rational behavior. We illustrate this general procedure with an example using uniform random behavior that allows researchers to test whether the actual number of violations of revealed preference is more consistent with uniform random behavior than rational behavior. This statistical test takes advantage of the fact that nonparametric revealed preference tests involve known prices and expenditures. Our illustrative example is accompanied by some Monte Carlo exercises showing that the uniform test performs very well. We implement our test using datasets from two well-known economic experiments. One is a dataset on altruistic choices from Andreoni and Miller (Econometrica 70:737–753, 2002). The second is a dataset on the choices made by subjects who act within a token economy from Battalio et al. (West Econ J 11:411–428, 1973) and Cox (Econ J 107:1054–1078, 1997). We find that for a majority of subjects in one altruistic behavior sub-experiment uniform random behavior can be rejected in favor of rational behavior at the 10 % level of significance. For all but one subject, living in the token economy, uniform random behavior cannot be rejected. For that one subject in the token experiment uniform random behavior is rejected in favor of perverse economic behavior.     

Ethnographic Heritage as a Branding Strategy: A Case Study of Yogurt in Bulgaria and Japan

Abstract

This article explores the various ways in which ethnographic images are deployed in branding strategies by Bulgarian and Japanese companies to frame industrial food as cultural heritage. Examining the history and marketing strategies of yogurt in Japan, I demonstrate how international marketing and cooperation has influenced the definitions, meanings and values of yogurt. In Japan, companies turn to ethnographic images of Bulgaria to sell their products, emphasizing visions of rural life over Bulgarian yogurt-making technology. At the same time, the fact that Bulgarian yogurt has turned into a symbol of health and wellbeing in one of the world’s economic powers is a source of national pride for consumers in post-socialist Bulgaria. The branding strategies of yogurt show how companies transform foods into culturally meaningful products, thereby doing much more than making profitable commodities of them. In educating and offering consumers new lifestyles, they change established systems of consumption and influence people’s imaginations.     

The scope and scale of the informal food economy of South African urban residential townships: Results of a small-area micro-enterprise census

Growing urbanisation in South Africa is reflected in burgeoning Working class and informal township settlements on the fringes of its major towns and cities. Paired with this is an increasing reliance on cash as the primary means of economic transaction, which has in turn stimulated the growth of micro-enterprise business activities within the township context. This article discusses the findings of an eight-township small-area census which occurred between 2010 and 2013 in Cape Town, Johannesburg, Ekurhuleni and Durban townships representing 250 000 residents. The researchers were able to establish the scope and scale of informal food and drink retailing in these localities. Of the 10 049 micro-enterprises located in the study, some 3966 (or 39% of the total) trade in food. These include enterprises in primary production, fresh produce retailing, grocery retailing from house and spaza shops, and informal foodservice enterprises. Food is the basis for much township informal business and plays an important role in making food increasingly affordable and locally accessible, and in creating cash employment. The article builds on the knowledge base of the township informal economy role in bolstering food security needs for the marginalised.
