Foreign direct investment and economic growth in Sub-Saharan Africa: A nonlinear analysis

Using the threshold regression model, we examine the effects of Foreign Direct Investment (FDI), and the mediating role of FDI absorptive capacity, on economic growth in Sub-Saharan Africa. We find that the threshold level of FDI inflows per person is approximately US$ 44.67 per annum. For FDI to have an appreciable impact on economic growth, countries must have minimum capacity to absorb the growth-enhancing benefits of FDI. For instance, the technology gap between the hosted foreign enterprises and domestic enterprises should be no less than 0.6904. Thus, achieving the FDI threshold level is a necessary, but not sufficient, condition for economic growth. Some countries use tax incentives to improve FDI inflows. We argue that such incentives may be counterproductive at low levels of FDI inflows: FDI coefficient estimates below the lowest threshold level are negative, implying that the higher costs of such incentives exceed the potential benefits availed by FDI’s direct contribution to economic output and spillovers.     

Welfare migration in Europe

The enlargement of the European Union has increased concerns about the role of generous welfare transfers in attracting migrants. This paper explores the issue of welfare migration across the countries of the pre-enlargement European Union and finds a significant but small effect of the generosity of welfare on migration decisions. This effect, however, is still large enough to distort the distribution of migration flows and, possibly, offset the potential benefits of migration as an inflow of mobile labour into countries with traditionally immobile native workers.     

Video-sharing platform's optimal monetary incentive decisions considering motivation crowding-out effect

Considering the motivation crowding-out effect of monetary incentives, a game-theoretic model is built to examine a video-sharing platform's optimal incentive decisions. Results show that offering monetary incentives to contributors does not ensure an improvement in video quality nor an increase in the platform's profit. We identify four ideal market conditions for the platform to offer monetary incentives. We find that though the motivation crowding-out effect seems to undermine the effectiveness of monetary incentives, the ideal market conditions for offering monetary incentives do not always require this effect to be very weak; sometimes it even has to be medium.     

Tax enforcement policies,tax evasion and time allocation

Several studies examine the effect of tax rates on households’ labor supply decisions in attempts to account for observed differences in work hours across countries. Interestingly, these studies fail to consider a fundamental action associated with taxation: tax evasion. This paper introduces, into a general equilibrium model of household labor supply, the possibility that households can evade labor income taxes. We show that the relationship between tax-enforcement policies, the elasticity of substitution between consumption and leisure and the elasticity of substitution between formal and informal work is key to explain formal labor supply in major OECD countries. In a model without informal work, there is a positive relationship between the elasticity of substitution and the tax rate on formal income and people tend to work more. This is the case for the United States, Greece, Finland and the United Kingdom. This relationship becomes negative once informal activities are introduced and the model can explain formal labor supply better in countries where agents work relative less, i.e., in Austria, Denmark, France, Germany, Spain, Norway and Sweden. We also obtain estimates of hours worked in the informal sector for these countries.     

Curbing cream-skimming: Evidence on enrolment incentives

Using data from a large, U.S. federal job training program, we investigate whether enrolment incentives that exogenously vary the ‘shadow prices’ for serving different demographic subgroups of clients influence case workers' intake decisions. We show that case workers enroll more clients from subgroups whose shadow prices increase but select at the margin weaker-performing members from those subgroups. We conclude that enrolment incentives curb cream-skimming across subgroups leaving a residual potential for cream-skimming within a subgroup.     

Rationality in supplier selection decisions: The effect of the buyer's national task environment

Our study sheds light on two fundamental questions in supply management: First, does adherence to highly rational decision processes help buyers make better supplier selection decisions? Second, is the influence of procedural rationality on decision effectiveness moderated by buyers’ (differently dynamic) task environments? We empirically test these questions using a sample of 150 supplier selection decisions taken in China and 150 decisions taken in Germany, countries that expose buyers to dynamic decision environments and stable decision environments, respectively. Our findings suggest that the influence of decision process rationality is stable across decision makers’ task environments. Both in China and in Germany, such process rationality is positively related with higher decision quality, and no significant differences in relationship strengths emerge between the two country samples.     

Comparing levels of anti-Muslim attitudes across Western countries

In this study we describe differences of the ethnic majorities?? attitudes toward Muslims across Western countries. Using data from the Pew Global Attitudes Survey (2005), we were able to increase and test cross-cultural comparability of anti-Muslim attitudes. We constructed a single factor CFA model with three indicators, which was tested for scalar equivalence. Our results indicate that anti-Muslim attitudes differ significantly across the countries in our analysis. Germany and the Netherlands turned out to display relatively high levels of anti-Muslim attitudes, whereas these levels were relatively low in Great-Britain and the USA. We conclude our study with giving some post-hoc explanations for the differences found across countries.     

Investment Incentives and Electricity Spot Market Competition

In this paper we analyze investment decisions of strategic firms that anticipate competition on many consecutive spot markets with fluctuating (and possibly uncertain) demand. We study how the degree of spot market competition affects investment incentives and welfare and provide an application of the model to electricity market data. We show that more competitive spot market prices strictly decrease investment incentives of strategic firms. The effect can be severe enough to even offset the beneficial impact of more competitive spot markets on social welfare. Our results obtain with and without free entry. The analysis demonstrates that investment incentives necessarily have to be taken into account for a serious assessment of electricity spot market design.

Why truck distance taxes are contagious and drive fuel taxes to the bottom

This paper analyzes the way in which countries with international and local truck traffic decide to switch from a simple fuel tax system to a dual system of fuel and distance charge taxes. We show what drives a country to switch and how this affects the level of fuel taxes as well as incentives for other countries to also adopt the dual system. The model is partially able to explain the gradual extension of kilometer charging for trucks in Europe. The model also shows that, in the absence of diesel cars, the gradual introduction of kilometer charges will make fuel taxation for trucks virtually disappear and will lead to a system where truck use is (1) taxed mainly based on distance, (2) is taxed too heavily, and (3) where highest distance taxes are expected in transit countries with a strong market position. When the fuel tax must in addition serve as an externality tax for diesel cars, the introduction of distance charges for trucks will give rise to diesel taxes that are lower than the external cost of diesel cars. For trucks, this leads to a sum of diesel taxes and distance charges that are higher than the external cost of trucks.     

Social dumping and relocation: is there a case for imposing a social clause?

Public opinion in Europe seems worried about the relocation of production plants toward low wage countries often accused of practicing ‘social dumping’. To reduce the incentives for relocation trade unions proposed the adoption of ‘social clauses’ protecting domestic markets from commodities produced in countries where minimal labor condition are not met. We analyze the effects of the adoption of a social clause in a vertically differentiated Bertrand duopoly. We assess how such a policy affects firms’ relocation decisions in order to be able to assess its welfare implications. We also characterize the optimal social clause policy, both under domestic welfare maximization, and from an efficiency point of view. While we show that a social clause policy cannot be dismissed on domestic (or world) welfare grounds, its case is weaker the higher is the domestic wage and the lower is the foreign wage.     

Firm leverage decisions: Does industry matter?

We use a standard capital structure mode l to investigate the firm leverage decisions of 1620 companies listed in the Australian Securities Exchange (ASX) across a span of 13 years (2000–2012), dividing the sample into mining and other industries (non-mining). We also test for significant differences in leverage decisions between these two groups by applying a dummy variable approach. Our findings show that fundamental differences exist between mining and non-mining companies when making leverage decisions. We find evidence that mining firms are more sensitive to profitability and asset tangibility where neither profitability nor asset tangibility has significant association for non-mining firms. Overall results suggest that industry-type does matter for firms making leverage decisions.     

The importance of financial incentives on retirement choices: New evidence for Italy

This study exploits a new dataset to quantify the effect of financial incentives on retirement choices. This dataset contains—for the first time for Italy—information on seniority. The effects of marginal incentives and social security wealth (SSW) on retirement go in the expected direction; when employees become eligible for pension benefits, the change in financial incentives they experience is so great that their retirement probability increases by 30 percentage points.We also find that the procedure used in previous Italian studies to impute seniority leads to a considerable overestimation of that variable and of SSW. We show that, due to these measurement errors, the estimate of the SSW coefficient takes the wrong sign. A comparison of retirement studies across countries (see Gruber and Wise [Gruber, J., and Wise, D., (2004). Social Security Programs and Retirement Around the World: Micro-Estimation, NBER. The University of Chicago Press, Chicago and London.]) provides prima facie evidence that a lack of good quality data often leads to wrongly signed estimates of the SSW coefficient.     

Cultural values and definitions of career success

This paper examines how national culture relates to the ways that individuals define career success. Data are drawn from interviews with 269 professional services employees in 15 countries. Interviews are content coded and linked with country‐level Global Leadership and Organizational Behavior Effectiveness measures of cultural values. We test our hypotheses using a multilevel multinomial logit model. The results demonstrate that the ways in which employees define career success vary across countries, due in part to differences in cultural values after controlling for gender, occupation, job level, and national economic development. We find that employees from countries high in future orientation, uncertainty avoidance, and performance orientation are more likely to define career success in terms of interpersonal outcomes, and those from countries high in collectivism (institutional and in‐group), humane orientation, and gender egalitarianism are more likely to prefer intrapersonal outcomes. We find that employees from countries that are high in assertiveness, uncertainty avoidance, and performance orientation are more likely to define career success in terms of achievement‐oriented outcomes. Finally, we find that employees from countries high in power distance report career success definitions in terms of safety and security outcomes. We discuss the implications of these findings for theories of cultural differences in careers across countries.     

Investment and Liquidation Incentives under Solvency Tests and Legal Capital

The European Union (EU) has been debating for several years whether to change from the legal capital regime as regulated under the Second Company Law Directive to a solvency test regime as applied in the USA, for example. Based on an analysis of direct compliance costs and capital maintenance systems in non-EU countries, the EU decided not to change the regulatory regime in the short term. This paper focuses on the indirect costs of these two regimes. The paper develops a model in which payouts are restricted by one of the two regimes and the equity holders have the choice between extending and liquidating the existing investments. I find that both regimes will create first-best incentives if their respective design parameters are properly balanced. Under a legal capital regime, however, first-best will be a random event, because accounting standards typically do not allow for the necessary interdepencies between the accounting for liabilities and investments. The advantage of a solvency test with respect to the implementation of first-best incentives diminishes if equity holders can misreport future prospects. Under the legal capital regime, misreporting incentives can be excluded by sufficiently conservative depreciation. A solvency test designed to achieve efficient decisions will always create incentives to overstate future cash flows.     

Centralized and decentralized provision of public goods

We model the trade-off between centralized and decentralized decision making on the provision of local public goods. Decisions are influenced by spillover effects and differences in jurisdictional size. Centralized decisions are made in a legislature of locally elected representatives, and this creates a conflict of interest between citizens in different jurisdictions. The legislature can be self-interested or benevolent and this can result in either efficient, excessive, or misallocative provision of public goods. The form of centralized decision making has a significant influence on the incentives for centralizing decision making.     

HOW SENSITIVE ARE RETIREMENT DECISIONS TO FINANCIAL INCENTIVES? A STATED PREFERENCE ANALYSIS

We study the effects of financial incentives on retirement decisions using stated preference data. Dutch survey respondents were given hypothetical retirement scenarios describing age(s) of (partial and full) retirement and replacement rate(s). A stylized model is estimated in which utility is the discounted sum of within‐period utilities that depend on employment status and income. Parameters of the utility function vary with observed and unobserved characteristics. Simulations show that the income and substitution effects of pensions as a function of the retirement age are substantial and larger than according to studies using data on actual retirement decisions in the Netherlands.

Investment and concern for relative position

Economists typically analyze individuals' market behavior in isolation from their nonmarket decisions. While this research strategy has generally been successful, it can lead to systematic errors when agents' nonmarket behavior affects their market choices. In this paper we analyze how individuals' investment behavior changes as a result of nonmarket behavior. Specifically, we analyze a model in which individuals must decide how to allocate their initial endowment between two random investments, where the returns are perfectly correlated across individuals for the first investment but independent across individuals for the second. We consider an environment in which men and women match, with wealthier individuals more successful in matching. We show how individuals' concern about relative wealth can affect their investment decisions, and we provide conditions under which individuals bias their investments either toward or away from the investment with correlated returns. A modification of the model is used to explain why agents' investments might exhibit a home country bias.     

Testing the Efficacy of Replacing the Incurred Credit Loss Model with the Expected Credit Loss Model

Abstract

We use a controlled laboratory environment to provide evidence on the potential efficacy of the replacement of the Incurred Credit Loss (ICL) Model of International Accounting Standard (IAS 39) by the Expected Credit Loss (ECL) model of IFRS 9 to account for credit impairment losses. We focus on the simplified version of the ECL model using an uncertain production environment as the context. We induce incentives consistent with the existing rigid rule-based ICL model and the proposed forward-looking principle-based ECL model. Our primary finding is that the combined effects of eliminating the minimum ‘probable’ threshold condition together with allowing managers to incorporate forward-looking information increase both the amount and adequacy of periodic reserve decisions. In addition, we analyze the effects of increased flexibility under the new credit-loss model on earnings management using three different compensation schemes. We find that while the replacement of the ICL model with the ECL model facilitates higher reserves, the resulting increased earnings management varies across compensation schemes, is less than predicted, and does not offset the potential of the ECL model’s positive effects. The results provide ex ante evidence on the likely intended and unintended consequences of implementing the ECL model.     

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.
