Labor market outcomes,savings accumulation,and return migration

In this paper, I examine the determinants of return migration from Germany for immigrants from four different source countries, and test the savings accumulation conjecture that is used to rationalize return migration decisions using both cross-country and time variation in purchasing power parity. The empirical results confirm the savings accumulation conjecture. Therefore, return migration can be seen as part of optimal life-cycle location choices in this context. I also examine how labor market outcomes influence return decisions. A key finding here is that unlike previous studies, which find a positive impact of unemployment on return migration, I find that the direction of the impact of unemployment changes by the spell length.     

Competing specifications of the gravity equation: a three-way model,bilateral interaction effects,or a dynamic gravity model with time-varying country effects?

We investigate bilateral trade flows across the EU-15 countries from 1962 to 2003 by different specifications of the gravity model. We augment the basic gravity model with population and exchange rate variables, and then include time-varying country fixed effects, to account for Anderson and van Wincoop (Am Econ Rev 93(1):170–192, 2003) multilateral resistance terms. Then, following the previous theoretical derivations of the gravity model in the presence of panel data in a dynamic setting we change the specification of our gravity model. We compare the results of different specifications showing the improvement in each case. We claim the comparative superiority of the dynamic gravity model with time-varying exporter and importer fixed effects due to its higher explanatory power. Finally, we compare out-of-sample forecasting performance of different specifications of the gravity model.     

Consumer Response to Package Downsizing: Evidence from the Chicago Ice Cream Market

It is common among producers of consumer packaged goods to reduce the volume of product per package such that the new size replaces the old one. This tactic is commonly referred to as package downsizing. In this article, we investigate the extent to which consumers have different sensitivities to package price and package size in order to shed light on the managerial implications of package downsizing. To do so, we estimate a random utility model of demand to measure consumer response to price and package size using household scanner panel data on bulk ice cream purchases in Chicago. The estimation framework involves modeling household heterogeneity, addressing price endogeneity and accounting for unbalanced choice alternatives. Our main finding is that consumers are less responsive to package size than to price; the demand elasticity with respect to package size is approximately one-fourth the magnitude of the demand elasticity with respect to price. This result implies that marketing managers can use downsizing as a hidden price increase in order to pass through increases in production costs, that is, cost of raw materials, and maintain, or increase, their profits.     

Generational analysis of leisure time physical activity participation of women in Turkey

The purpose of this study was to analyse the adolescent-period leisure time physical activity (LTPA) experiences of three generations of women within the framework of the socio-ecological model and feminist cultural studies. For this purpose, we conducted semi-structured interviews with 144 women from three generations (48 girls, 48 mothers of the girls, and 48 grandmothers of the girls) and subjected the data to thematic analysis using a constant comparison method. Four themes were organized to assess similarities and differences across three generations drawing on the socio-ecological model: 1) Changing the meaning of sports, LTPA and being active; 2) Social resources for participating in LTPA: From authoritarian to supportive parenting; 3) Doorsteps, streets and the four-walls; and finally: 4) Changing educational policy. The findings revealed that, in parallel with the multifaceted historical changes in Turkey, the individual, social, physical environment and political factors of socio-ecological model determine the women’s LTPA participation differed throughout the generations. Results also showed that gendered relations continue to influence LTPA participation of women across the generations.     

Asymmetric response to monetary policy surprises at the long-end of the yield curve

This paper investigates the responsiveness of asset markets to monetary policy path revisions. Using federal funds futures contracts to extract near-term path revisions, we find that the responsiveness of longer term Treasury securities to path revisions is significantly asymmetric, the magnitude of which increases during tightenings and decreases during easings. These findings blend nicely with the earlier literature that documents asymmetric effects of monetary policy on output.     

Uncertainty representation and risk management for direct segmented marketing

ABSTRACT

Mining for truly responsive customers has become an integral part of customer portfolio management, and, combined with operational tactics to reach these customers, requires an integrated approach to meeting customer needs that often involves the application of concepts from traditionally distinct fields: marketing, statistics, and operations research. This article brings such concepts together to address customer value and revenue maximisation as well as risk minimisation for direct marketing decision-making problems under uncertainty. We focus on customer lift optimisation given the uncertainty associated with lift estimation models, and develop risk management and operational tools for the multiple treatment (recommendation) problem using stochastic and robust optimisation techniques. Results from numerical experiments are presented to illustrate the effect of incorporating uncertainty on the performance of recommendation models.     

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.     

Manipulation Through Biased Product Reviews*

We study a signal-jamming model of product review manipulation in which rational consumers consult product reviews and price to better estimate a product's quality, and a firm, whose quality is either high or low, chooses its price and how much bias to insert into product reviews. We show that both firm types always exert positive effort to manipulate product reviews, and, depending on the equilibrium price level, one or both of them can increase its sales. When the high-type firm exerts more effort than the low-type, review manipulation benefits consumers by raising [lowering] their demand for the high-quality [low-quality] product.     

Re-examining the threshold effects in the inflation–growth nexus with cross-sectionally dependent non-linear panel: Evidence from six industrialized economies

This paper analyzes the empirical relationship between inflation and output growth using a novel panel data estimation technique, Panel Smooth Transition Regression (PSTR) model, which takes account of the non-linearities in the data. By using a panel data set for 6 industrialized countries that enable us to control for unobserved heterogeneity at both country and time levels, we find that there exists a statistically significant negative relationship between inflation and growth for the inflation rates above the critical threshold level of 2.52%, which is endogenously determined. Furthermore, we also control cross-section dependency by using the CD test modified to non-linear context and remedy cross-section dependency with Seemingly Unrelated Regression Equations through Generalized Least Squares (SURE-GLS) and newly proposed Common Correlated Effects (CCE) estimation techniques. We find that these methods change the critical threshold value slightly. The estimated threshold values from these estimation methods are 3.18% and 2.42%, respectively.
