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.     

Misallocation,informality, and human capital: Understanding the role of institutions

The aim of this paper is to quantify the role of formal-sector institutions in shaping the demand for human capital and the level of informality. We propose a firm dynamics model where firms face capital market imperfections and costs of operating in the formal sector. Formal firms have a larger set of production opportunities and the ability to employ skilled workers, but informal firms can avoid the costs of formalization. These firm-level distortions give rise to endogenous formal and informal sectors and, more importantly, affect the demand for skilled workers. The model predicts that countries with a low degree of debt enforcement and high costs of formalization are characterized by relatively lower stocks of skilled workers, larger informal sectors, low allocative efficiency, and measured TFP. Moreover, we find that the interaction between entry costs and financial frictions (as opposed to the sum of their individual effects) is the main driver of these differences. This complementarity effect derives from the introduction of skilled workers, which prevents firms from substituting labor for capital and in turn moves them closer to the financial constraint.     

Promoting the informal sector as a source of gainful employment in developing countries: insights from Ghana

Although the informal sector continues to be the main source of employment in developing countries, little empirical research has been conducted into the human resource management (HRM) issues surrounding this sector in sub-Saharan Africa. Against this background, this study seeks to highlight the HRM issues, such as training and employment strategy, which are assuming increasing importance in the informal sector in developing countries. After reviewing the marginalist and structuralist debates on the informal sector, the paper looks at the Ghanaian government's attempt to transform the sector into a source of national economic development, entrepreneurship and self-employment. As part of this examination, the paper explores the question of whether the government's strategies can provide jobs for all who need them.

Based on the evidence of the empirical research, the paper argues that although the current Ghanaian government's informal employment strategy is a product of political expediency and, therefore, prone to pitfalls, it nevertheless constitutes a worthwhile attempt to combat unemployment in the long term. The paper also contends that in environments of perpetual economic crisis, which undermine the ability of sub-Saharan African (SSA) governments to generate adequate growth, it makes good socio-economic sense to promote the informal sector as a significant source of employment. The government's strategy should, therefore, be seen as an attempt to help the informal sector generate a level of employment above the marginal and survival. In this respect, the Ghanaian experience provides useful lessons for other SSA countries grappling with similar unemployment problems.     

Pollution and informal economy

In this study, we investigate the relationship between the size of the informal economy and the level of environmental pollution/energy use. To this end, we first use different indicators of environmental pollution along with a measure of energy use intensity in a panel dataset consisting of 152 countries over the period 1999–2009 and empirically examine the relationship between pollution and the shadow economy. The estimation results show that there is an inverse-U relationship between the size of the informal economy and environmental pollution, that is, small and large sizes of the informal economy are associated with lower environmental pollution and medium levels of informality are associated with higher levels of environmental pollution. Next, we build a two sector dynamic general equilibrium model to suggest an economic mechanism for this observation. Our model identifies two channels through which informality might affect environmental pollution: The scale effect, whereby a larger (smaller) informal economy size is associated with a lower (higher) level of environmental pollution, and the deregulation effect, whereby a larger (smaller) informal economy is associated with higher (lower) pollution levels. As these two effects work in opposite directions, the changing relative strength of one with respect to the informal sector size creates the inverted-U relationship between pollution indicators and informality.

Foreign direct investment and productivity spillovers in the Chinese manufacturing sector

In this paper a simple simultaneous model is constructed to examine whether there are productivity spillovers from both the presence of foreign direct investment (FDI) and competition between local and foreign firms. The model is tested on the data from China’s latest industrial census in 1995. The results indicate that the extent to which spillovers occur varies with different types of ownership of local firms and of FDI. While collective- and private-owned enterprises benefit from demonstration and contagion effects from foreign presence, productivity gains of state-owned enterprises largely come from competition with foreign firms. Productivities of local and foreign firms are jointly determined. Evidence also suggests that market-oriented FDI tends to generate spillovers mainly via competition with local firms.     

Socio-demographics,political attitudes and informal sector employment: A cross-country analysis

In this paper, we empirically investigate the relationship between informal sector employment and micro-level socio-demographic characteristics, political acts and attitudes, and individual norms. Using self-reported individual micro-level data from the World Values Survey for seven developing countries (China, Ecuador, Egypt, Mexico, Peru, South Africa and Yemen), our cross-country regressions and principal component analysis reveal that socio-demographic characteristics of individuals are strong predictors of their informal sector employment. Our estimations further document that individual preferences for an economically strong, interventionist and egalitarian state and confidence in state and political institutions are positively and significantly correlated with informal sector employment, whereas variables associated with confidence in free market institutions and support for competition are negatively and significantly correlated with informal sector employment. We also show that individuals who participate either actively or inactively in peaceful and lawful political processes are significantly less likely to work in the informal sector. Finally, we document that individual norms, such as religiosity and tax morale, are negatively correlated with informal sector employment. Throughout our analysis, instead of having to rely on ad-hoc informality categorizations of third parties, we base our measurement of informal sector employment directly on the self-evaluation of individuals, who have the best information on the degree of their informality.     

Speaking to Theorists and Searching for Facts: Tax Morale and Tax Compliance in Experiments

A significant body of research has been accumulated concerning tax morale and tax compliance. This paper takes a stroll through the experimental findings, focussing on personal income. After briefly discussing the traditional topic of deterrence the main focus is on the social and institutional factors which until now have received only limited attention.     

个税起征点改革对纳税能力的影响：基于居民收入分布的估算

本文分析了个税起征点变动对纳税能力的影响机理。本文基于2005~2012年我国居民收入分组数据,采用构建的收入分布纳税能力测算积分模型和PLS路径模型,估算了我国居民个人所得税纳税能力和个税起征点改革对纳税能力的影响效应。研究发现,2005年以来我国居民平均收入水平有较大的提高,收入分布呈厚尾分布特征,其标准差呈弱平的倒“U”形变化趋势。2006年和2008年两次个税起征点的调整并没有改变纳税能力的增长态势,却影响着税务部门的征缴行为,税收努力指数的波动表明,税制改革与征纳税人预期行为的强关联关系,2011年的个税起征点改革对纳税能力有较大影响;PLS路径模型估计显示,居民收入的增长对纳税能力影响最大,个税起征点改革则是通过增加居民收入、影响征缴行为来间接地影响纳税能力。     

The importance of being networked: The costs of informal networking in the Western Balkans region

This is the first study to measure the size and costs of informal networking, quizzing the premise that informal networks benefit individuals, households and entrepreneurs. On the basis of survey data from the Western Balkans (WB) and empirical analysis, we establish that informal networking, or use of personal contacts for getting things done, has a regular occurrence in the region and its economic cost is substantial. In the structure of networking costs, the costs of invested time dominate over money. Respondents who perceive networking as important and beneficial tend to invest more time and money to maintain their networks. Higher costs are associated with larger networks, which are predominantly built on strong ties. The informal networking costs are also higher for those with better education and income, and in particular for entrepreneurs. Consequently, individuals bear the high costs of informal networking not only for social and culturally determined reasons, but to a large extent for instrumental purposes. Our data suggest that both sociability and instrumentality drive informal networking, which makes it an outcome of both informal constraints (taboos, customs, traditions, and codes of conduct) and inefficient formal rules (constitutions, laws, property rights).

Tax aggressiveness and idiosyncratic volatility

This study finds that aggressive tax strategies adopted by a firm affect idiosyncratic stock return volatility. Aggressive tax strategies, which I measure as tax paid by a firm divided by pretax income (adjusted for special items), are associated with higher levels of idiosyncratic stock volatility. Uncertainty associated with tax strategies may result due to several factors, such as penalties, fines, and additional tax payments if particular tax strategies are disallowed by taxation authorities, or if there are changes in tax rules. Such uncertainty affects the future cash flows of a firm and is reflected in more volatile stock returns. Financial constraints, corporate governance mechanisms, and information environments surrounding a firm influence the relation between idiosyncratic volatility and effective tax rates.     

A supply-demand model of public sector size

We develop a supply-demand model for the public sector with a political equilibrium. The model considers the inefficiencies caused by taxes and includes costs associated with the provision of public goods to consumers. We show that the size of the public sector may depend on the median voter's income, population size, costs associated with paying tax, and quality of institutions, all of which reflect the costs of provisioning public goods. The estimates for the Organisation for Economic Co-operation and Development member countries are compatible with theoretical predictions; however, they do not confirm Wagner's law, which holds that the public sector share does not grow with an increase in income. A greater dependency ratio and the Gini coefficient increase demand for redistribution policies. Greater government effectiveness is a supply-side factor that increases the public sector's share in an economy.     

Some deadweight losses from the minimum wage: the cases of full and partial compliance

This paper highlights the social costs from non-price rationing of the labour force due to the minimum wage. By short-circuiting the ability of low reservation-wage workers to underbid high-reservation wage workers, the minimum wage interferes with the market's basic function of grouping the lowest cost workers with the highest productivity firms. The present paper models the deadweight loss that society bears when high reservation-cost workers displace low reservation-cost workers. When firms can evade part or all of the minimum wage, an extra deadweight loss arises. Firms with high evasive ability but low productivity may displace firms with low evasive ability but high productivity.

Tax morale: Framing and fairness

Tax morale has been a focus of academics and policy makers for some time. The measurement of individuals’ tax morale is subjective, and various proxies have been employed in qualitative and quantitative research. The framing of these measures has been considered in some research with respect to equivalency or goal framing, but the underlying implication of emphasis framing in commonly used proxies has yet to be considered. Further, although fairness and financial literacy have been considered determinants of tax morale, no one has yet considered whether financial and tax literacy (FTL) has a moderating effect on fairness and tax morale.This research addresses these gaps in the literature. The findings suggest that questions and scenarios posed by academics and policy makers should consider positive, negative, and emphasis framing, as well as the moderating effect of the respondents’ FTL to measure individuals’ tax morale effectively. The findings also suggest that raising levels of FTL could have a double dividend: not only will improved FTL have a positive impact on tax morale, but it might be magnified through the impact of fairness. These findings hold only when morale is determined by negatively framed scenarios. In particular, the perceived fairness of the tax system enhances tax morale when FTL is high, whereas the perception of fairness has no effect on tax morale for respondents with lower levels of FTL.     

Efficiency wages,wage comparison,and public sector budgeting

We develop a government decision model where efficiency wage mechanisms affect the allocation of resources between different public services. We show how the introduction of interdepartment wage relativities modifies the standard Solow wage setting conditions. We compare the outcome under centralised and decentralised wage setting, and show that a decentralised wage setting system creates a distortion. Finally, we discuss the possibility of elimination this distortion using alternative financing systems.Final version: 08 April 2003JEL Classification: H23, J45We are grateful to Jan E.

Output and productivity growth in the education sector: comparisons for the US and UK

This paper considers the measurement of performance in public service provision in an international context by examining outcome-based measures for the education sector. It first sets out the measurement issues in general terms. The paper then applies these methods to comparing the UK experience with that in the US over the period 1979–2002. The results show higher labour productivity growth in the UK education sector than in the US over this time period, so that the UK eliminated the productivity gap with the US by the end of the Century.

Electronic mail,privacy, and the public sector: Guidelines for public employees and organizations

What privacy rights are public employees entitled to when using their electronic mail systems? Are they entitled to privacy rights in the messages they send or receive? The setting, public or private, is crucial to determine what privacy rights exist for the employee. Unfortunately, no public sector electronic mail privacy case has been considered by the courts. Nevertheless, E-mail privacy guidance does exist. This article investigates previous privacy considerations provided in other workplace situations—cases that involve technologies other than E-mail—in search for common rules established by the Supreme Court. With this foundation, the article then applies the same rules to an electronic mail environment and provides guidelines intended to assist public managers in the creation or reevaluation of their organization’s electronic mail privacy policy.
