Geographic labour mobility and the cost of housing: evidence from Italy

In recent years, internal migration in Italy has declined markedly, notwithstanding the widening of the North-South gap in terms of unemployment rates and real income. Here, the extent to which the housing market has contributed to the decline is examined. Preliminary to this analysis, differentials in the cost of housing between the macro-areas of the country are estimated using data on the market price of houses located in 96 provincial capitals. Econometric evidence is provided supporting the view that the North-South housing price differential is a notable factor in explaining the falling pattern of mobility. The positive impact on migration from the South to the North of a wider gap in the two areas in terms of income and employment prospects has been offset by the housing price differential, which has steadily risen at least from the mid-1980s onwards. Yet, a considerable share of the decrease in mobility remains unexplained, possibly owing to the heterogeneity in the composition of migration flows across different cohorts.     

Sectoral shifts, diversification and regional unemployment: evidence from local labour systems in Italy

Using Local Labour Systems (LLSs) data, this work aims at assessing the effects of sectoral shifts and industry specialization patterns on regional unemployment in Italy over the years 2004–2008. Italy represents an interesting case study because of the high degree of spatial heterogeneity in local labour market performance and the well-known North–South divide. Furthermore, the presence of strongly specialized LLSs (Industrial Districts, IDs) allows us to test whether IDs perform better than highly diversified urban areas thanks to the effect of agglomeration economies, or viceversa. Building on a semiparametric spatial auto-regressive framework, our empirical investigation documents that sectoral shifts and the degree of specialization exert a negative role on unemployment dynamics. By contrast, highly diversified areas turn out to be characterized by better labour market performances.     

Experimental evidence on tax salience and tax incidence

Although a basic theoretical principle in public economics assumes that individuals optimize fully with respect to the introduction of a tax, a growing body of research is proving that several heuristics are in place when people take decisions. We re‐examine the well known liability side equivalence principle in the light of the concept of salience. While these two topics have been extensively investigated in isolation, this paper innovates on the previous literature in that it focuses on their joint effects. Is tax incidence dependent on whether the subjects face a salient rather than a nonsalient tax? Does the salience of a tax exert a different effect depending on who is legally committed to bear the tax burden? We address these questions through a laboratory experiment in which one unit of a fictitious good is being traded through a double‐auction market institution. Based on a panel data analysis, our contribution shows that point of collection matters and determines the economic incidence of tax. Additionally, we find that the joint effect of salience and statutory incidence does not alter the informative efficiency, but has a positive effect on buyers’ allocational efficiency when the tax is levied on sellers.     

The learning path of the hidden economy: the tax burden and tax evasion in New Zealand

This paper considers the ‘learning curve’ relationship between the aggregate tax rate and the relative size of the hidden economy in New Zealand. Some simple non-linear models are estimated so that the effects of changes in the effective tax rate on the underground economy can be simulated. This study finds that about half of the hidden activity in New Zealand is a learned response to changing opportunities and constraints in fiscal policy, but this amount varies over the business cycle. Simulating a zero tax rate permits us to discover the ‘natural rate’ of underground and criminal activity. Some partial lessons are drawn for taxation policy in that country.     

The pedagogy of tax evasion: Its extent and its determinants

This pedagogical note develops a model of individual choice and a comprehensible and functionally realistic framework that explains how the size of the underground economy or the extent of aggregate income tax evasion can be estimated. It also describes three models for estimating the size of the underground economy for the U.S. and provides a formal but easily understood analytical model of determinants of the extent of aggregate income tax evasion. The latter model is useful in serving as the basis for empirical estimates of determinants of income tax evasion and is useful in enhancing student understanding economic behavior through student projects.     

Optimal taxes on wealth and consumption in the presence of tax evasion

This article incorporates tax evasion into an optimum taxation framework with individuals differing in earning abilities and initial wealth. We find that despite the possibility of its evasion a tax on initial wealth should supplement the optimal nonlinear income tax, given a positive correlation between initial wealth and earning abilities. Further, even if income and initial wealth are taxed optimally, it is still desirable to levy a tax on commodities, though it can be evaded as well. Thus, our result provides a rationale for a comprehensive tax system. Optimal tax rates on commodities differ in general, however for the special case of a uniform evasion technology equal rates are optimal if preferences are homothetic and weakly separable.     

Quasi-experimental evidence on the effectiveness of heart attack treatment in Germany

ABSTRACT

Medical technological progress has been shown to be the main driver of health care costs. A key policy question is whether new treatment options are worth the additional costs. In this analysis we assess the causal effect of percutaneous transluminal coronary angioplasty (PTCA), a major new heart attack treatment, on mortality. We use a full sample of administrative hospital data from Germany for the years 2005 to 2007. To account for non-random treatment assignment of PTCA, instrumental variable approaches are implemented that aim to randomize patients into getting PTCA independent of heart attack severity. Instruments include differential distances to PTCA hospitals and regional PTCA rates. Our results suggest a 4.5 absolute percentage point mortality reduction for patients who have access to PTCA compared to patients receiving only conservative treatment. We relate mortality reduction to the additional costs for this treatment and conclude that PTCA treatment is cost-effective in lowering mortality for AMI patients at reasonable cost-effectiveness thresholds.     

A contest with the taxman - the impact of tax rates on tax evasion and wastefully invested resources

We develop a moral hazard model with auditing where both the principal and the agent can influence the probability that the true state of nature is verified. This setting is widely applicable for situations where fraudulent reporting with costly state verification takes place. However, we use the framework to investigate tax evasion. We model tax evasion as a concealment-detection contest between the taxpayer and the authority. We show that higher tax rates cause more evasion and increase the resources wasted in the contest. Additionally, we find conditions under which a government should enforce incentive compatible auditing in order to reduce wasted resources.     

The effect of migration on black incomes: evidence from the 1940 census

"Evidence from the 1940 [U.S.] census reveals that southern-born blacks who left the region prior to 1935 had higher incomes than non-southern born blacks. The income gap between migrants and non-migrants declined with schooling."     

The co-evolution of tax evasion,social capital and policy responses: a theoretical approach

The dynamic model presented in this paper intends to account for the evidence, which appears to be particularly significant for Italy, of the incidence of tax evasion in a certain region being negatively correlated with the level of social capital existing in that region. Besides including social capital among the determinants of tax evasion, we extend the model so as to incorporate a mechanism whereby the existing volume of opportunistic behavior—which is proxied by the level of tax evasion—has negative effects on the formation of new social capital, thus helping to explain how regional differences in the endowment of social capital and in the incidence of tax evasion co-evolve and why they tend to be highly persistent. The model seeks also to capture the fact that in a democracy the political determination necessary to effectively repress tax evasion depends on the voters’ propensity toward the phenomenon. Hence, one should expect that–in areas where a relatively large (small) number of citizens are tax cheaters—the consensus in favor of tough policies against tax evasion tends to be weak (strong) and short (long) lasting. Consistently with this intuition, the model shows that regions where social capital is relatively low and tax evasion is relatively high can do better in the long run (i.e., they can reach a steady state characterized by a higher level of social capital and a lower level of tax evasion) when tax-enforcement policies are determined at the national level rather than at the regional level. The opposite holds for regions where social capital is relatively high and tax evasion is relatively low.     

Evaluating innovation and labour market relationships: the case of Italy

In this paper the link between labour market flexibility andinnovation is analysed paying particular attention to the differenttechnological regimes of economic activities and the differentgeographical areas of the Italian economy. A dynamic panel dataspecification is used to assess the endogenous relationshipbetween patents, included as a proxy for innovation, and jobturnover and wages, which represent labour market indicators.Our results show that higher job turnover only has a significantand negative impact on patent activities in regional sectorsof Northern Italy, while blue and white collar wages have beengenerally found to have a positive and significant impact oninnovation.     

Numerical simulation on property tax reform: evidence from China

This article analyses the property tax reform in China in a computable general equilibrium model that recognizes the interaction between and among housing markets in different provinces and macroeconomic development. Using real data in 2010, we present the benchmark equilibrium for reference property and income tax rates. Then, we examine different property and income tax policies and make a comparison of their production, consumption, welfare and national income. We find that the implementation of property tax would decrease the house production at the expense of welfare in taxed area. The expansion of the taxed regions may increase the total social welfare and national income. Even though property tax policy may not be able to change the income distribution in China, increasing income tax rate could narrow the income disparity. Finally, this article shows the reliability of the conclusions when sensitivity analysis on optimal condition of equilibrium computation is performed under varied property tax policy.     

Keeping it off the books: an empirical investigation of firms that engage in tax evasion

This article uses a unique dataset that contains detailed information on firms from around the world to investigate factors that affect under-reporting behaviour. The empirical strategy employed exploits the nature of the dependent variable, which is interval coded, and uses interval regression which provides an asymptotically efficient estimator provided that the classical linear model assumptions hold. These assumptions are investigated using standard diagnostic tests that have been modified for the interval regression model. Evidence is presented that shows that the firms in all regions engage in under-reporting. Regression results indicate that government corruption has the single largest causal effect on under-reporting, resulting in the percentage of sales not reported to the tax authority being 51.3% higher. Taxes have the second single largest causal effect on under-reporting, resulting in the percentage of sales not reported to the tax authority being 18.0% higher, followed by access to financing at 8.9% higher and organized crime at 7.6% higher. Inflation, political instability, exchange rates and the fairness of the legal system were found to have no effect on under-reporting. It is also found that there is a significant correlation between under-reporting and the legal organization of the business, size, age, ownership, competition and audit controls.     

Outsourcing of accounting tasks and tax management: evidence from a corporate tax rate change

The aim of this article is to investigate if small firms react to a national corporate tax rate reduction by managing their taxable income. In contrast to previous studies, we also analyse whether outsourcing of accounting tasks affects the magnitude of the reaction. Based on a sample of Finnish firms and measures of earnings management, evidence is provided that firms with an internalized accounting function are more active tax planners in this context. This study suggests that outsourcing of accounting tasks increases the corporate tax reporting quality.     

Firm-sponsored training in regulated labour markets: evidence from Spain

Using data from the 1994 European Community Household Panel Survey, the author examines who receives formal firm-sponsored training in Spain. The author finds that the distribution of firm-sponsored training in the work force is uneven and concentrated among more skilled workers in the upper deciles of the wage distribution. The data show that the likelihood of receiving firm-sponsored training for a low education employee is much lower. Also, the better-educated employees in high wage occupations of the largest establishments have higher probabilities of receiving specific training. Spain has a highly regulated labour market, and the labour market frictions and institutions compress and distort the structure of wages. However, the results suggest that the highly compressed wage structure do not provide firms with the incentive to invest in general training.     

Innovation and weak labour disposability: some theoretical and empirical evidence

This paper envisages theoretically and empirically the weak labour disposability and the ability of labour to innovate in a poor-capital, surplus-labour economy. Therefore, a production function where the marginal product can become zero or even negative has been derived and estimated using data from Suden over the period 1968–88, with quarterly interpolation. Thus, unlike neoclassical specifications of endogenous growth theory, labour withdrawal may have minimal effect on output. The results indicate the presence of weak disposability of labour. The existence of a discernibly low capital–saving technical relationship between labour and capital has been verified using cointegration techniques.     

The effect of fertility on labour force participation: The Spanish evidence

Abstract. The aim of this paper is to estimate the effect of fertility on the decision of labour force participation of married females in Spain, allowing for the existence of unobserved characteristics that affect both fertility and participation. We use a pooling of five waves of the European Household Panel for Spain (1994–1998). Results indicate that not taking into account the unobserved characteristics that affect both variables imposes on average a strong downward bias on the true effect of fertility on participation. This bias is especially strong for highly educated females. We are grateful to Raquel Carrasco and an anonymous referee for helpful comments.

Corporate tax avoidance and cost of equity capital: international evidence

ABSTRACT

This study examines the association between firm’s tax avoidance activities and cost of equity capital across 17 countries. Consistent with the prior study based on the U.S. evidence, within strong investor protection countries, the extent of firm’s tax avoidance is negatively associated with its cost of equity capital. This result indicates that strong investor protection induces investors to perceive firm’s tax avoidance activities as the results of efficient tax planning to reduce tax liabilities. To the contrary, we find that the extent of firm’s tax avoidance is positively associated with its cost of equity capital within weak investor protection countries. This result suggests that investors impose equity risk premium on firm’s tax avoidance activities in weak investor protection countries, where agency conflicts prevail more on firm’s tax avoidance activities. As the first international study on the association between firm’s tax avoidance activities and its cost of equity capital, this study contributes to the literature by suggesting that such an association may vary across countries depending on the strength of investor protection within each country of domicile.     

Impact of income tax on happiness: evidence from the United States

The present work considers the level of demonstrated happiness and unhappiness within groups, the latter measured by the conditional probability of suicide within groups facing an income tax rate and those without. Using US data for the year 2004, our results show that individuals have lower rates of suicide or are ‘happy’ when they do not pay income taxes than those who pay.
