Small producers,supermarkets, and the role of intermediaries in Turkey's fresh fruit and vegetable market

A wide range of empirical studies show the extent to which the rise of supermarkets in developing countries transforms domestic marketing channels. In many countries, the exclusion of small producers from so‐called dynamic marketing channels (that is, remunerative ones) has become a concern. Based on data collected in Turkey in 2007 at the producer and the wholesale market levels, we show that intermediaries are important to understanding the impact of downstream restructuring (supermarkets) on upstream decisions (producers). Results show first that producers are not aware of the final buyer of their produce, because intermediaries hinder the visibility of the marketing channel, thereby restricting a producer's choice to that of the first intermediary. Econometric results show that producers who are indirectly linked to the supermarkets are more sensitive to their requirements in terms of quality and packaging than to the price premia compensating the effort made to meet standards. Therefore, the results lead us to question the role of the wholesale market agents who act as a buffer in the chain and protect small producers from negative shocks, but who stop positive shocks as well, and thereby reduce incentives.     

Evaluating spatial and temporal variation in agricultural output elasticities in Turkey

This study evaluates spatial variation in the relationship between agricultural output and input use across Turkey. The potential impact of the national agricultural policy reform introduced in 2001 on the spatial variation in agricultural output elasticities across the country was explored. By applying a spatial production function to the province‐level data in 2000 and 2007, spatial heterogeneity in the variance of provincial total factor productivity and the input factor‐output elasticities was identified across the country. Results show that the disparities in agricultural activities and geographic conditions affected return from input factors. Empirical findings from a spatial spillover model also suggest that changes in the input factor‐output elasticities varied significantly across Turkey between 2000 and 2007, after the policy reform. Results suggest that future policy reform that recognizes regional comparative advantage through understanding the geographic heterogeneity of the agricultural sector is important for enhancing Turkey's agricultural output.     

Temporal dynamics of trust in ongoing inter-organizational relationships

This paper reports the results of a qualitative study undertaken to understand the nature of trust and its consequences for both suppliers and buyers in short term (relatively new) and long term (older/more mature) relationships in inter-organizational contexts. Scholars have recently pointed out the importance of research that investigates the temporal characteristics and dynamics of trust in inter-organizational studies. Our paper responds to this call by indentifying the changing nature of the level of trust as the buyer–supplier relationship matures. Our findings contribute to sparse and conflicting previous research on the relationship between length of partnership and perceptions of trust, types of dark side consequences of trusting relationships, and reasons buyers and suppliers continue or terminate low/no-trust associations. Specifically, we illustrate that buyers and suppliers draw on substantially different metaphors for understanding the nature of trust in long and short term exchange relationships. Suppliers see marked differences in trust with long term versus short term exchange partners, while buyers see little or no difference. Suppliers and buyers also appear to have different conceptions of how trust is nested (or not) within the broader economic and/or personal relationship. Through our inductive model, we elaborate several types of betrayal and disappointment, distinguish several factors that lead suppliers and buyers to stay in relationships with partners they don't trust, and identify key issues that topple untrusting relationships into terminated relationships.     

The message in the box: how exposure to money affects charitable giving

Does donation box transparency matter in regard to donation behavior? The purpose of this research is to test the effect of donation box transparency on potential donors’ charitable behavior. In a series of experimental studies, including a field experiment, data were collected on willingness to donate and donation amount in three treatments: a wooden donation box (opaque condition), transparent donation box containing very little money, and transparent box almost full of money. Participants in the transparent box treatment were both less willing to donate money and they donated less money compared to subjects in the opaque box treatment. Moreover, data was collected to demonstrate that participants in the transparent box conditions experienced a heightened state of self-sufficiency due to the effect of money exposure. Implications are discussed for theory development and future research avenues and in terms of practical considerations for charity organizations.     

The Split of the S&P 500 Futures Contract: Effects on Liquidity and Market Dynamics

The Chicago Mercantile Exchange reduced the size of its S&P 500 futures contract when it reduced the multiplier from 500 to 250 and increased the minimum tick from 0.05 to 0.10 on November 3, 1997. This is a rare major change in a very successful contract's specifications. We analyze effects of this change on liquidity and market dynamics in both a univariate and a multivariate context. The main contribution of this study is the use of multiple intervention analysis with various dynamic response functions to examine the effects of the split while taking into account several other major market events surrounding it. A multivariate analysis is also used to test the impact of the split using a structural model of liquidity and market dynamics. Empirical findings offer limited support for the hypotheses that smaller contract size resulted in smoother trading, and that more public customers trade the S&P 500 futures contract following its split. We observe a reduction in the average transaction size as well as a temporary narrowing of the bid-ask spreads, but no significant change in volatility that can be attributed to the split. We do not find any significant and lasting impact on other liquidity and market variables.     

Optionality and Daily Dynamics of Convenience Yield Behavior: An Empirical Analysis

In this article I empirically examine the daily convenience yield behavior for six commodity markets (crude oil, heating oil, gasoline, wheat, corn, and copper). The results illustrate that convenience yield behavior can be statistically explained within an option pricing framework. However, because one of the assumptions of the standard call option formula is not fully satisfied by the observed convenience yield series, an alternative option—exchange option—may be more appropriate for modeling the daily convenience yield behavior. Furthermore, I empirically test two hypotheses on convenience yield behavior. The results confirm the assertion that the convenience yield is increasing in marginal production costs. In addition, the findings offer limited support for the hypothesis that the convenience yield is decreasing in the serial autocorrelation of spot prices. The observed switch in the sign of regression coefficients as the order of autocorrelation increases is attributed to the probable presence of mean reversion in these markets.     

Social and political components of economic performance for the 1960s: A note on Adelman and Morris' ‘society,politics and economic development’

The influence of a given sociopolitical setting on the subsequent economic performance of the LDCs is examined. For this purpose, non-economic indicators developed by Adelman and Morris and two indices of economic activity, per capita gross national product and per capita energy consumption, are used. Component and regression analysis show that in the short run, a given sociopolitical setting significantly affects subsequent economic activity. The results enable a broadening of some of Adelman and Morris' findings.     

Regulate one service,tame the entire market: Credit cards in Turkey

In credit card markets banks provide both payment and credit services. Two regulations were recently enacted in the Turkish credit card market: one on payment services in 2005 and the other on credit services in 2006. By employing the well-known  and  method and a unique quarterly data set for 21 Turkish banks between 2002 and 2008, we investigate the extent of banks’ market power in the Turkish credit card market before and after the regulations. Unlike most of the existing literature, which considers competition and regulation for either credit or payment services and ignores the externalities between them, we consider the entire market by taking both services into account. Fixed effects estimations reveal that banks enjoyed collusive oligopoly power before the regulations. Although the first regulation did not have much impact, the second led to rises in both banks’ total revenues and competition in the entire market.     

The effectiveness of technology-assisted history teaching based on peace training: The case of history of Cyprus

Changes in history education in Europe are related to the new approaches in the field of education, particularly related to the usage of technology in education. Additionally, the interest in the history of war, which originated as a result of the previous world wars, has been replaced by peace education today. This study is based on the principles of peace education and is based on an eight-week educational process that was implemented in the 2016–2017 spring semester. The study sample was 11 secondary school students who were enrolled at a private school in Nicosia, Northern Cyprus. In order to collect data during the research period, student essays, the Cyprus history attitude scale and researcher observation reports were used. Qualitative data obtained in the research were evaluated using content analysis, whereas quantitative data were evaluated with the Wilcoxon signed-rank test. At the end of the study, it was determined that students expressed interest in receiving education on the history of Cyprus teaching in an environment that incorporates technology, which also reduces the necessity for memorizing details and political history, and where socio-cultural history is more prevalent. Researcher observations show that the awareness of students for peace education increased and their historical empathy and cooperative working skills were developed. However, despite such positive results, it was also discovered that there is no significant difference in quantitative terms in the attitude of students towards the history of Cyprus.
