Welfare impacts of new demand-enhancing agricultural products: The case of Honeycrisp apples

Agricultural research and development programs on new demand-enhancing products have become increasingly important over the past decade. Large numbers of new agricultural products have been developed and commercialized in the United States to meet consumers’ increasingly diverse expectations for food quality. However, little is known about their economic benefits. Focusing on the apple market, we investigate the welfare impacts of the introduction of Honeycrisp apples in a market equilibrium framework. We use market data on apple sales from 61 cities across the United States between 2009 and 2015. We find the introduction of Honeycrisp increased consumer welfare, which is mainly explained by the increased number of total apple varieties. We also find that the introduction of Honeycrisp apples has increased overall market size and total apple sales. To extrapolate our results to the entire U.S. apple market, we perform a back-of-the-envelope analysis and find that the introduction of Honeycrisp apples has increased total consumer welfare by about 859 million dollars during the study period. This corresponds to approximately 19% of the annual average domestic expenditures on public food and agricultural R&D.     

LOCAL LABOR MARKETS,JOB MATCHING,AND URBAN LOCATION*

We present a new way of modeling local labor markets by linking the space of workers' skills and the physical space of cities. The key lesson of our analysis is that firms exploit workers in these two spaces by setting wages that are below the competitive level. The degree of monopsony power depends on the elasticity of the firm's labor pool, which is inversely related to the costs workers incur in commuting and acquiring skills. Our analysis thus shows how socioeconomic ghettos emerge as workers with poor skill matches are also those who incur the highest commuting costs.     

Business cycle co-movements between South Africa and the BRIC countries

This article examines the relationships between South African economy and the economies of the BRIC (Brazil, Russia, India and China). In particular, it identifies the nature and key features of the co-movement of South African business cycles with cycles of the BRIC countries. It uses the dynamic factor model to a set of 307 macroeconomic series during the period 1995Q2 to 2009Q4. We found significant evidence of synchronization between South Africa and the BRIC countries over the business cycle, although the magnitude of co-movement differs with each country. India portrays strong ties with South Africa over time. Moreover, Brazil, China and Russia lead South Africa in the long run, while India is contemporaneous. Further, the findings imply that the first two factors are BRICS factors while the third one is a US factor.     

Border Crossings between Georgia and Turkey: The Sarp Land Border Gate

The Sarp land border gate between Turkey and Georgia has become Turkey’s gateway to the East in recent years. With a large number of individuals crossing every day, it is also a labour gate, where irregular Georgian immigrants cross the border for work in Turkey. In general, border policies are constructed and reconstructed in a dynamic process in which economic, security, ethnopolitical, geopolitical and cultural paradigms interact. The aim of this paper is to observe the complementary and conflicting relationship and negotiation process between economic and security paradigms in particular, with a focus on the perceptions of the officers of the border administration and state bureaucracy at the local level. To this end, field research was carried out consisting of interviews with Turkish state officials responsible for immigration and border crossing in the Sarp gate region. The article sheds light on the interaction between various agencies, actors and stakeholders in border policymaking at the regional level. It also elaborates on the profiles both of incoming immigrants employed as irregular workers and of deportees. The results of the qualitative study show that the dominance of the economic paradigm that underlies the main framework of Georgia-Turkey relations overrides security concerns between the two countries, thus necessitating a more flexible implementation of laws. The field research illustrates that implementation of laws and regulations at the local level varies and while some groups of irregular immigrants are allowed to work, others are not and, what is more, are deported.     

Nonlinearity and nonstationarity in international art market prices: evidence from Markov-switching ADF unit root tests

This study investigates the presence (or lack thereof) of nonlinear dynamics and nonstationarity in international art market prices using quarterly data for the period 1990–2011. We first test whether art market price indices follow stochastic trends or whether they are stationary by means of linear unit root tests. Next, we estimate the Markov regime-switching ADF model and test whether the linear or the nonlinear regime-switching model provides a better characterization of the global art market price series. We find that all art market price indices (except for Drawings) exhibit nonlinearity. To our knowledge, our study is the first one in the literature to suggest that a nonlinear (Markov regime-switching) model provides a better characterization of the behavior of price dynamics in international art markets. In particular, our findings indicate that the market for the overall global art market, paintings, old masters, sculptures, photographs, prints, and contemporary art might indeed be stationary while exhibiting nonlinear regime-switching properties. On the other hand, the market for drawings and the Nineteenth century art are found to be nonstationary. Overall, despite the common ground of a regime-switching framework, we still find that the sub-segments of the art market have their own inner regime switching dynamics and hence they can evolve differently overtime.     

An empirical study on the nexus between the emotional intelligence of top managers and their assessment of intellectual capital

This study considers intellectual capital based on the assumption that this capital, which possesses social aspects, is related to the emotional capacities (i.e., emotional intelligence) of an organization’s members. A literature review indicates that this relationship has been previously noted and studied, and researchers agree that the emotional intelligence of the members of an organization affects the organization’s intellectual capital. Based on this analysis, this relationship is examined in the Turkish business context. Data are collected from top managers, who can affect the intellectual capital oftheir businesses and who, as human beings, are emotional. Thus, in this study, the emotional intelligence of top managers and their opinions regarding the intellectual capital of their businesses are considered to be related, with interesting results. When all of the factors of emotional intelligence that are likely to affect opinions regarding intellectual capital are examined using a multivariate model, the effect of emotional intelligence is revealed. Primarily, three factors of the emotional intelligence—empathy and communication skill, self-awareness and sociability—affect the participants’ opinions regarding the intellectual capital of their businesses. Univariate models are used to evaluate the effect of each emotional intelligence factor on the participants’ opinions regarding the intellectual capitalof their businesses. Empathy and communication skills affect opinions about the quality of human capital. Self-awareness affects opinions about the organizational commitment of workers. Sociability can affect opinions about information technology and information sharing. In summary, emotional intelligence affects opinions about human capital quality, information technology and information sharing.     

Help the Low Skilled or Let the Hardworking Thrive? A Study of Fairness in Optimal Income Taxation

In a model where agents have unequal wages and heterogeneous preferences, we study the optimal redistribution via an income tax, when the social objective is based on a combination of efficiency and fairness principles, and when incentive issues are taken into account. We show how some fairness principles entail specific features for the optimal taxes, such as progressivity or tax exemption for incomes below the minimum wage.     

Political Business Cycles and Partisan Politics: Evidence from a Developing Economy

This paper explores whether the evidence supports the Political Business Cycle (PBC) theory, Partisan Theory (PT), and Rational Partisan Theory (RPT) using stock market data from Turkey, a rapidly growing developing economy. The results indicate that the PBC hypothesis is not supported by the data. We find permanent partisan effects in the conditional variance but not in returns. The conditional volatility of the returns is higher during the periods in which a leftist party or a coalition government is in office. We also find that the stock market returns temporarily decreases (increases) at the beginning of a right‐wing (left‐wing) government, providing evidence in favor of RPT.     

An integrated model for stock replenishment and shipment scheduling under common carrier dispatch costs

We examine a joint inventory replenishment and shipment scheduling problem that arises in the context of a vendor-managed inventory (VMI) arrangement. Since a temporal shipment consolidation policy is being implemented, the inventory requirements at the vendor are affected by the timing and quantity of shipment release. The vendor’s problem is to determine an integrated policy for inventory replenishment and shipment release and to set its parameters. We develop analytical models for computing such integrated policies where it is economical to use common carriage for outbound transportation. We propose algorithmic approaches to set the optimal policy parameter values.
