Substitution Elasticity

Abstract This paper discusses measurement of the elasticity of substitution between goods from different countries. To remedy potential endogeneity problems in regression estimations, we use the instrumental variables (IV) approach, and the Feenstra method that does not require the use of instruments. The commodities that we study here and for which we were able to find relevant instruments are bovine, swine, and poultry meat imports by Japan. We find that the two approaches yield very similar results for these commodities. Further, upon extracting the implicit IVs of the Feenstra method, we find them as useful as the external IVs for measuring the aggregate of foreign commodities with a fixed effects regression and for estimating the foreign-domestic substitution elasticity possibly for each commodity.

Despite the important role of adult parent–child and sibling relations in the family system, only few studies have investigated yet, how the common adult experience of parental death impacts sibling relations. Estimating fixed-effects regression models using four waves of data from the German Family Panel (pairfam; n = 4,123 respondents), the present note focused on changes in three dimensions of adult siblings’ relationship qualities following the first parent’s death. Our analysis revealed a short-term positive effect of parental death on sibling contacts as well as longer-lasting increases in emotional closeness and conflicts. Next to an intensification of sibling relations following the first parent’s death, we also detected significant spillover effects from respondents’ relationship with the surviving parent to their sibling relations. Our analysis thus provided evidence for adult parent–child and sibling relations to be “linked in life and death,” underlining the benefits of jointly analyzing intra- and intergenerational family relationships.

Abstract Government agencies often encounter problems in service delivery when implementing public programs. This undermines effectiveness and raise questions about accountability. A central component of responsiveness and performance management is that agencies correct course when problems are identified. However, public agencies have an uneven record in responding to problems. In this paper we investigate whether, and to what extent, capacity both within the agency and within institutions performing oversight, improves agency responsiveness to poor performance indicators. Using panel data on eligibility determinations in the Social Security Disability program from U.S. state agencies from 1991-2015 and fixed effects regression, we find that indicators of agency and oversight capacity moderate the relationship between poor performance and improvement. Our results suggest that investments in building capacity not only within agencies, but also within elected institutions, are important for successful policy implementation. However, we find evidence that while agency capacity alone can improve responsiveness to poor performance, the effect of oversight capacity on improving performance requires high agency capacity.

Establishment Survey

Abstract Using a unique employee–establishment survey, we find a causal relationship between an individual employee’s trust of management and their decision-making rights (delegation). We utilize both fixed effects (FE) and instrumental variables to control for unobserved factors: establishment-level FE control for management quality, practices, culture, and other characteristics; our instruments of inherited trust in management, and trust of equivalent workers in a different but similar country address the possible endogeneity of employee trust. Across all specifications, we find that delegation to a worker is more likely if that employee trusts management. In our preferred model, which includes establishment FE and accounts for endogeneity, we find a 1 standard deviation (SD) increase in employee trust increases delegation by approximately 0.6 of 1 SD. Our results are robust to the inclusion of worker preferences for individualism (which favors delegation), incentives/bonuses, and alternative measures of decision authority. (JEL D23, L22, L23).

Purpose – The purpose of this study is to examine the effect of boards’ demographic diversity on firms’ strategic change and the interaction effect of firm performance. Design/methodology/approach – This paper used secondary data derived from publicly listed firms in Kenya during 2002-2010 and analyzed the data using fixed effects regression model to test the effect of board demographic and strategic change, while moderated regression analysis was used to test the moderating effect of firm performance. Findings – The results partially supported board demographic diversity–strategic change hypothesis. In particular, results indicate that age diversity produces less strategic change, while functional diversity is associated with greater levels of strategic change. The moderated regression results do not support our general logic that high firm performance enhances board demographic diversity–strategic change relationship. In effect, the results reveal that at high level of firm performance, board demographic diversity produces less strategic change. Originality/value – Despite few studies that have examined board demographic diversity and firm performance, this paper introduces strategic change as an outcome variable. This paper also explores the moderating role of firm performance in board demographic diversity–strategic change relationship, and finally, the study uses Kenyan dataset which in itself is unique because most governance and strategy research uses data from developed countries.

This paper analyzes the effect of the so-called ‘brain drain’ on economic growth through the channel of growth in total factor productivity. We analyze panel data that measure the severity of brain drain, which are from IMD and the U.S. National Science Foundation. Our analysis shows that middle-income countries have more brain drain compared to the group of high-income countries. Also, emerging economies that grow fast tend to experience more brain drain. Our results from fixed effects regression models show that that brain drain has a significant and positive impact on economic growth, and the main channel is productivity growth. This can be considered as evidence of the positive effects of ‘brain circulation’, which is one of the brain drain phenomena that settlement of the talents in advanced countries can eventually help improve the productivity of home country by the sharing of advanced technologies and skills around them with colleagues in motherland. Therefore, a strategy of utilizing overseas resident talents should also be considered, alongside the brain-attraction policy.

The study analyzed effects of bank-specific, industry-specific and macroeconomic determinants on banks profitability. It used a maximum of 350 firm-years, from 52 banks from 1998 to 2010 in Tanzania. It did proxy profitability using return on asset (ROA), return on equity (ROE) and net interest margin (NIM). The static fixed effects regression model indicated that; credit facilities (CFA), capital adequacy (TEA), credit risk (CFR), diversification ratio (DIV), bank risk (BAR) and financial market development (MCAd) were significantly influencing ROA. The dynamic fixed effects regression model indicated that lagged ROA, TEA, loan losses provisions (PLT) and BAR, were significantly influencing ROA.

BackgroundIn late 2020 a second wave of COVID-19 infections occurred in many countries and resulted in a national lockdown in the UK including stay at home orders and school closures. This study aimed to compare the prevalence of psychological distress before and during the second COVID-19 wave in the UK. MethodsThis study drew on data from 10,657 participants from the nationally representative probability-based UK Household Longitudinal Study (UKHLS). The 12-item General Health Questionnaire (GHQ-12) assessment measure was used to detect the proportion of UK adults experiencing clinically significant psychological distress. Changes in distress levels associated with the second pandemic wave were examined between September 2020 and January 2021 using logistic regression and linear fixed-effects regression models. ResultsLongitudinal analyses showed that the prevalence of clinically significant distress rose by 5.8% (95% CI:4.4-7.2) from 21.3% in September 2020 to 27.1% in January 2021, compared with a 2019 pre-pandemic estimate of 21% in this cohort. Fixed effects analyses confirmed that the second COVID-19 wave was associated with a significant within-person increase in distress (d =0.15, p<.001). Increases were particularly pronounced among those with school-age children in the home. LimitationsA non-specific measure of mental health symptoms was utilized and it was not possible to separate the potential impact of the pandemic from other changes occurring in tandem within the study period. ConclusionClinically significant distress rose during the second wave of the COVID-19 pandemic and reached levels similar to those observed in the immediate aftermath of the first pandemic wave.

Consequences Of Obesity

AbstractObesity is thought to significantly impact the quality of life. In this study, we sought to evaluate the health consequences of obesity on the risk of a broad spectrum of human diseases. The causal effects of exposing to obesity on health outcomes were inferred using Mendelian randomization (MR) analyses using a fixed effects inverse-variance weighted model. The instrumental variables were SNPs associated with obesity as measured by body mass index (BMI) reported by GIANT consortium. The spectrum of outcome consisted of the phenotypes from published GWAS and the UK Biobank. The MR-Egger intercept test was applied to estimate horizontal pleiotropic effects, along with Cochran’s Q test to assess heterogeneity among the causal effects of instrumental variables. Our MR results confirmed many putative disease risks due to obesity, such as diabetes, dyslipidemia, sleep disorder, gout, smoking behaviors, arthritis, myocardial infarction, and diabetes-related eye disease. The novel findings indicated that elevated red blood cell count was inferred as a mediator of BMI-induced type 2 diabetes in our bidirectional MR analysis. Intriguingly, the effects that higher BMI could decrease the risk of both skin and prostate cancers, reduce calorie intake, and increase the portion size warrant further studies. Our results shed light on a novel mechanism of the disease-causing roles of obesity.
