Effects of treatment beyond the treated: a general equilibrium impact evaluation of Lesotho's cash grants program

Africa's social cash transfer programs target the most resource‐constrained households, unlikely to expand supply in response to transfer‐induced demand. We propose a local economy‐wide impact evaluation model and use it to evaluate local spillovers from Lesotho's Child Grants Program. We report Monte‐Carlo confidence bounds around impact‐simulation results. We find significant spillovers to nonrecipient households and significant real income multipliers, although the latter are dampened if factor supply constraints generate excessive inflationary pressures. Our findings raise questions about how to measure the impacts of cash transfers. Evaluations focusing only on eligible households are likely to significantly understate program impacts.     

Stakeholder Multiplicity: Toward an Understanding of the Interactions between Stakeholders

While stakeholder theory has traditionally considered organization’s interactions with stakeholders in terms of independent, dyadic relationships, recent scholarship has pointed to the fact that organizations exist within a complex network of intertwining relationships [e.g., Rowley, T. J.: 1997, The Academy of Management Review 22(4), 887–910]. However, further theoretical and empirical development of the interactions between stakeholders has been lacking. In this paper, we develop a framework for understanding and measuring the effects upon the organization of competing, complementary and cooperative stakeholder interactions, which we refer to as stakeholder multiplicity. We draw upon three forms of fit (i.e. fit as matching, fit as moderation, and fit as gestalts; Venkatraman, N.: 1989) to develop a framework for understanding stakeholder multiplicity based upon the direction, strength, and synergies of the interacting claims. Additionally, we draw upon the theory of stakeholder identification and salience of Mitchell et al. (1997), which we argue provides a more relevant and significantly more illustrative explanation of the nature and effects of stakeholder interactions upon the organization than the network approach of Rowley (1997). Furthermore, we ground our framework through reference to three stakeholder groups (i.e. governments, customers, and employees) and the stakeholder issue of concern for the natural environment. We propose a hierarchy of the multiplicity strength of influence of these three stakeholder groups. Potential measurement and implications are discussed.     

Inefficient trade patterns: Excessive trade, cross-hauling and dumping

I study an example of a competitive environment in which trade occurs in a sequential manner. In this example, a country with a stable demand may suffer from trade with a country with unstable demand, there may be too much trade, a country may import and export the same good in the same period (cross-hauling) and dumping may occur. The timing of delivery is important. When delivery occurs before trade (delivery to stocks), trade improves welfare, there is dumping but no cross-hauling. When delivery occurs after trade (delivery to order), trade may reduce welfare and cross-hauling may occur.     

Varianzquotiententests und Random Walk Verhalten internationaler Aktienmärkte

Variance ratio tests can be considered the state-of-the-art methodology for testing stock markets for random walk behavior. This article reviews recent developments in the area. Furthermore, it analyzes whether the recent financial crisis has influenced the random walk behavior of international stock markets. Our findings based on individual and multiple variance ratio tests can be summarized as follows: (i) There appears to be less evidence against the random walk hypothesis in industrialized markets than there is in emerging markets. (ii) Industrialized countries’ stock market behavior seems to be less affected by the financial crisis than the one of emerging markets. (iii) The choice of individual or multiple variance ratio test does not crucially influence our main conclusions.     

Revisiting the democracy-private investment nexus: Does inequality matter?

Contrary to the predictions of a large theoretical literature, recent cross-country evidence suggests autocracies can generate statistically indistinguishable levels of private investment compared to democracies. We argue that the previous exclusion of inequality explains part of this puzzle. We model current investment as a function of investors’ beliefs about future tax rates, which are conditioned by the constraints on the Executive in setting tax rates and expropriating tax revenues. In democracies, where tax rates reflect the preferences of the median voter, investment declines with rising inequality. In autocracies, investor beliefs about future tax rates reflect the relative power of Elites compared to the Executive. As inequality rises, the increased resources available to Elites constrains the Executive’s ability to expropriate more tax revenues. The heterogeneous determinants of investor beliefs can explain the observed pattern of investment across regime types. We first test our predictions at the macro-level with cross-country data. We then test the behavioral underpinnings of our model with a novel laboratory experiment showing how inequality affects individual-level investment behavior dependent upon regime type. Results from both types of analyses show that when inequality is taken into account autocracies can generate similar levels of investment to democracies.

Human capital and youth emigration in the “new normal”

Every society's future lies in its youth, which can be considered a critical milestone for a nation's sociopolitical development. This research examines the young population attempting to identify and explores the students' perceptions about migration, their postulates, and the reasoning why so many students ultimately choose to emigrate. Data were collected in a questionnaire survey of 206 randomly selected students from Bosnia and Herzegovina. Some different multivariate analyses were performed to test the hypotheses. Other results were further discussed. Results show that the country's legal framework is a key reason for the prevailing poor living standard. This has resulted in a large number of youths leaving the country. Overall, both the legal framework (for both young entrepreneurs and women) and the overall standard of living (quality of life, well-being, salary, retirement, and education) are correlated with people choosing to emigrate. Furthermore, theoretical and practical implications are discussed. As far as we know, this is the first empirical study on this particular region that investigates the youth migration trends considered an important milestone for human capital development.

Employer risk-adjustment transitions with inertial consumers: Evidence from CalPERS

Risk-adjustment policies, which transfer money from insurers with healthy consumers to those with sick consumers, are an important tool to contend with adverse selection in health insurance markets. While the steady-state properties of risk-adjustment have been studied extensively, there is less evidence on the transition phase of policy implementation. We study the introduction and removal of risk-adjustment at California Public Employees' Retirement System and show that these changes meaningfully impact premiums via plan differences in enrollee health status. Despite these premium differences, there is limited consumer resorting due to consumer inertia, though new active enrollees respond more fluidly. We show that, with inertial consumers, risk-adjustment changes have substantial distributional consequences, leading to worse outcomes for sicker consumers when removed and vice-versa when implemented. We estimate a model of plan choice with premium sensitivity, brand preferences, and inertia and use these estimates to study the interaction between risk-adjustment policies and the strength of inertia.
