Income diversification,wealth, education and well-being in rural south-western Madagascar: Results from the Mahafaly region

Rural households in the Mahafaly region of south-western Madagascar have to contend with low economic development and a risky natural environment. A survey of 665 households in the region was designed to address three research questions: what is the relationship between diversification of income sources and household wealth; how does education influence access to non-farm income sources and diversification; and how does household wealth and diversification affect well-being? The results show that the overwhelming majority of households follow a diversification strategy. Household wealth is associated with larger fields, greater crop diversity and higher diversification of income source categories. Education enhances access to high-return, non-farm income sources. Self-reported well-being is positively affected by both wealth and diversification. Better education and measures to improve inhabitants’ existing strategies for compensation of yield losses in farming are crucial for securing local livelihoods in the face of decreasing precipitation due to climate change.     

Firm Size and Work Compensation in China

Remarkably, recent research on the Chinese labor market has suggested that the situation in China is inconsistent with the stylized fact that large firms pay higher wages and offer more generous benefits. Expanding the empirical basis from 78 to 300 000 industrial firms, I overturn theprevious result andshow that wage determination in the averagefirmfits the international norm. Exploring subsamples of firms I also point to a likely source for the conflictingfindings： firm size is positively correlatedwith the average wage in private firms, but negatively correlated with the average wage in the state-owned sector. These novel results couM guide future studies aiming to understand the sources of the firm size wage premium, and, in particular, studies that target the largest industrial labor market in the world     

Global Distortions to Agricultural Markets: Indicators of Trade and Welfare Impacts, 1960 to 2007

Despite recent reforms, world agricultural markets remain highly distorted by government policies. Traditional indicators of those price distortions such as producer and consumer support estimates (PSEs and CSEs) can be poor guides to the policies' economic effects. Recent theoretical literature provides scalar index numbers of trade‐ and welfare‐reducing effects of price and trade policies which this paper builds on to develop more‐satisfactory indexes that can be generated using no more than the data used to generate PSEs and CSEs. We then exploit a new Agricultural Distortion database to provide time‐series estimates of index numbers for 75 developing and high‐income countries over the past half‐century.     

Bankable emission permits under uncertainty and optimal risk-management rules

This article proposes a theory of banking of emission permits under conditions of regulatory uncertainty. Based on a two-period partial equilibrium framework, we examine the effects of increasing risk–in the sense of a mean preserving spread–regarding a future permit allocation at the firm level. We also examine the role of an agency to pool risks by re-allocating permits for a group of firms. Our results are twofold. First, an increase in risk may lead to changes in a firm’s banking strategy, depending on the third partial derivative of its production function with respect to pollution. Second, we define an optimal risk-sharing rule between agents to respond to political decision changes. Our results overall suggest that the bankability of permits may be used as a risk-management tool.     

BUSINESS CYCLES AND ADMISSIONS TO SUBSTANCE ABUSE TREATMENT

We study the effect of business cycles on admissions to specialty substance abuse treatment using administrative data between 1992 and 2015. We proxy business cycles with the state unemployment rate and apply a panel fixed‐effects model. While previous economic research has shown that substance abuse is counter‐cyclical, we observe no change in the total number of admissions across the business cycle. However, focusing on average effects misses important heterogeneity. In substance‐specific regressions we find statistically significant evidence that heroin‐related admissions are counter‐cyclical while stimulant‐related admissions are procyclical. Our findings add to the literature on business cycles and health. (JEL I1, J2)     

New product and service launching in new ventures: a multilevel approach to innovation antecedents

Macro-economic policies such as public financing seek to push the development and introduction of innovations; however, entrepreneurs also need support in their ‘day-to-day’ activities to improve their capability to launch innovations. As this micro-level perspective is rarely studied, we analyze both the micro and macro levels by examining the effects of the entrepreneurs’ individual intention to innovate and public financing. Additionally, we include the meso level, representing entrepreneurs’ network. Entrepreneurs are embedded in social spheres in which they capture resources and identify opportunities. But not all entrepreneurs are equally well supported, and some tend to be completely isolated. We thus focus on multilevel factors explaining new product or service launching in new ventures. Drawing on data of 48,251 French new ventures, we reveal that innovation intention and public financing positively impact new ventures’ product and service innovation launching, while entrepreneurs’ isolation has a negative effect. We also highlight two interaction effects that enhance the multilevel effects of innovation antecedents.     

System‐Spanning Values Work and Entrepreneurial Growth in Family Firms

Culture and values are key drivers of corporate entrepreneurship in early stages of family firm development, but value conflicts often arise over time that progressively inhibit their entrepreneurial efforts. How can family firms reconcile conflicting values to sustain corporate entrepreneurship over time? Our 45‐year longitudinal case study of a large global family firm shows that family business leaders’ practices of invoking and flexibly using family and business values were crucial to achieve sustained entrepreneurial behaviour and growth over an extended period of time. We theorize these efforts as system‐spanning values work enfolding through specific family, business, and temporal mechanisms. By identifying and elucidating three types of values work (i.e., rooting, revitalizing, and spreading), our study advances current understanding of the micro‐foundations underpinning the relationship between values and entrepreneurship in family firms.     

Eco‐innovation motivations and ecodesign tool implementation in companies in the Nordic textile and information technology sectors

The current sustainability challenges and the required systemic transformation highlight the need for innovations on multiple levels. Ecodesign integrates environmental aspects into product and process design to reduce environmental impacts, whereas eco‐innovation also concerns nontechnological solutions. In this paper, we formulate a model that combines eco‐innovation targets ad mechanisms with sustainability maturity, which also concerns stimuli and barriers faced by companies and ecodesign tools used. The results are based on a questionnaire sent to 902 textile and information technology (IT) companies (N = 104) in the Nordic countries. The tools that Nordic textile and IT companies use in particular are life cycle assessment, type I ecolabel, and carbon footprint. Internal stimuli, especially general willingness, were important for eco‐innovativeness, while legislation and customer demand also pushed companies forward. Specific no‐go barriers were not identified, although increase in costs was a common barrier. The respondents focus often on technological product innovations, but rarely on functional innovation, renting of products, and so forth. This highlights the need to address the availability of the right kind of tools to support a broader suite of innovation that can drive toward the circular economy.     

Vaccination under pessimistic expectations in clinical trials and immunization campaigns

We provide one of the first formalizations of a vaccination campaign in a decision-theoretic framework. We analyze a model where an ambiguity-averse individual must decide how much effort to invest into prevention in the context of a rampant disease. We study how ambiguity aversion affects the effort and the estimation of the vaccine efficacy in clinical trials and immunization campaigns. We find that the behaviors of individuals participating in a clinical trial differ from individuals not participating. Individuals who are more optimistic toward vaccination participate more in trials. Their behaviors and efforts are also affected. As a result, because vaccine efficacy depends on unobserved behaviors and efforts, the biological effect of the vaccine becomes difficult to evaluate. During the scale-up phase of a vaccination campaign, provided that vaccine efficacy is established, we show that vaccine hesitancy may still be rational.
