The marginal cost of public funds and the flypaper effect

A lump-sum intergovernmental transfer has a “price effect”, as well as an “income effect”, because it allows the recipient government to reduce its tax rate, which lowers its marginal cost of public funds, while still providing the same level of public service. This reduction in the effective price of providing the public service helps to explain the “flypaper effect”—the empirical observation that a lump-sum grant has a much larger effect on spending than an increase in personal income. Contrary to the assertions of Mieszkowski (Modern Public Finance, 1994) and Hines and Thaler (J. Econ. Perspect. 9:217–226, 1995), a model of a benevolent local government financing its expenditures with a distortionary tax predicts flypaper effects from lump-sum grants that are similar to those observed in many econometric studies.     

An evasive topic: theorizing about the hidden economy

This paper reviews some central issues that arise in theorizing about tax evasion decisions and the hidden economy. It starts from the Allingham and Sandmo (J. Public Econ. 1:323–338, 1972) modeling of the tax evasion decision as a choice under uncertainty based on expected utility maximization and risk aversion. It goes on to discuss alternative specifications of the taxpayer’s preferences with particular regard to the explanation of the extensive margin, i.e. the decision on whether or not to engage in tax evasion. It extends the model to the case of variable labor supply with work in both official and black labor markets. It then considers the application of the theory to taxes on wealth and income from capital, indirect tax evasion, and smuggling. It also includes a consideration of general equilibrium effects and of the problems that evasion causes for the theory of optimal income and commodity taxes. It concludes with a brief discussion of the implications of tax evasion for economic policy in the welfare state.     

Valuation before and after tax in the discrete time, finite state no arbitrage model

We establish necessary and sufficient conditions for a linear taxation system to be neutral—within the multi-period discrete time “no arbitrage” model—in the sense that valuation is invariant to the exact sequence of tax rates, realization dates as well as immune to timing options attempting to twist the time profile of taxable income through wash sale transactions.

“In the study of investments, taxes are largely a source of embarrassment to financial economists.” (Introduction to Dybvig and Ross 1986) “Accordingly, my approach in this chapter is to examine the restrictions on the income measurement rules applicable to financial instruments implied by the requirement that the rules be linear. . . . Linearity is a desideratum of a tidy tax system.” (Bradford 2000, p. 373–374)

     

Measuring, explaining, and controlling tax evasion: lessons from theory, experiments, and field studies

In this paper, I assess what we have learned about tax evasion since Michael Allingham and Agnar Sandmo launched the modern analysis of tax evasion in 1972. I focus on three specific questions and the answers to these questions that have emerged over the years. First, how do we measure the extent of evasion? Second, how can we explain these patterns of behavior? Third, how can we use these insights to control evasion? In the process, I illustrate my own answers to these questions by highlighting various specific examples of research. My main conclusion is that we have learned many things but that we also still have many gaps in our understanding of how to measure, explain, and control tax evasion. I also give some suggestions—and some predictions—about where promising avenues of future research may lie.     

No significant service gap between west Germany and the USA

Conclusions The analyses show that a significant “services gap” does not exist between west Germany and the USA. Such a gap is not even evident in the area of low-skill service activities, such as in catering, once the marginal employment relations — the importance of which is understated by the official statistics — are included. This finding invalidates the empirical basis for economic policy proposals for an expansion of employment in service branches as a way out of the employment crisis. It is evident that a solution to Germany's current employment problems can only be found in a strategy that increases the scope for employment at the macro-economic level, i.e. irrespective of sectoral developments and whatever the implications of this for the distribution of the various types of activity. Having said this, the heavy bias in the output structure of the German economy in favour of industrial output suggests that an additional employment potential does exist in services, especially personal services.     

Universal bounds for asset prices in heterogeneous economies

We establish universal bounds for asset prices in heterogeneous complete market economies with scale invariant preferences. Namely, for each agent in the economy we consider an artificial homogeneous economy populated solely by this agent, and calculate the “homogeneous” price of an asset in each of these economies. Dumas (Rev. Financ. Stud. 2, 157–188, [1989]) conjectured that the risk free rate in a heterogeneous economy must lie in the interval determined by the minimal and maximal of the “homogeneous” risk free rates. We show that the answer depends on the risk aversions of the agents in the economy: the upper bound holds when all risk aversions are smaller than one, and the lower bound holds when all risk aversions are larger than one. The bounds almost never hold simultaneously. Furthermore, we prove these bounds for arbitrary assets.      

Poverty traps and intergenerational transfers

In this paper, by adopting an OLG neoclassical growth model, we show that intergenerational transfers may trigger the take off of an economy entrapped into poverty in a twofold way: (1) by eliminating the zero equilibrium, which, under technology with low factor substitutability, is always a “catching” point, so that the economy might start converging to a positive equilibrium. In this case, the appropriate instrument turns out to be a transfer from the old to the young, while there is no room for policies redistributing in the opposite direction (i.e., a pay-as-you-go pension scheme); (2) when the rich equilibrium is unstable—which can be the case under high intertemporal elasticity of substitution of individuals—the introduction of transfers may stabilize such an equilibrium, so that the economy starts converging to it. In the latter case, both policy programs such as pay-as-you-go pension schemes or subsidies to the young may help escaping from poverty. However, we point out that in either circumstance, the “size” of transfers should be sufficiently large (and, as for pensions, not even too large), in order to avoid ineffective and useless burden on the taxpayers without triggering the take off.      

Shadow economies around the world: novel insights, accepted knowledge, and new estimates

This paper is a first attempt to study the impact of enforcement on the shadow economy. Using a MIMIC model, we find that a higher share of sub-national government employment and the aspiration of public employees to follow rules significantly deter shadow economic activities. Our results also confirm previous findings: Increased burdens of taxation and regulation as well as the state of the “official” economy are important determinants of the shadow economy. The estimated weighted average informality in 162 countries around the world, including developing, Eastern European, Central Asian, and high-income OECD countries, is 17.1% of “official” GDP.     

Structural Breaks and the Convergence of Regional House Prices

This paper differs from past research by examining the issue of whether regime changes have broken down the stability of the ripple effect. The endogenous two-break LM unit test, derived in Lee and Strazicich (Review of Economics and Statistics 85: 1082–1089, 2003), is used to execute the ripple effect tests. Being different from the empirical results of the conventional unit root tests without structural breaks, the empirical results of the endogenous two-break LM unit root test support the existence of ripple effects for each city in Taiwan except Taipei City. Shocks to regional house prices of Taipei City cannot “ripple out” across the nation, because Taipei City is a regional global city which has resulted in higher house prices, but does not affect the house prices of the entire area. Furthermore, the empirical evidence demonstrates the breakpoints and presents real estate policies, financial crises, and natural disease that can cause structural breaks of regional house prices.     

Information Sharing and International Taxation: A Primer

The sharing between national tax authorities of taxpayer-specific information has emerged over the last few years as a—probably ‘the’—central issue on the international tax policy agenda. Yet this refocusing of the debate on international taxation—away from parametric tax coordination and towards strengthening information exchange—has gone largely unnoticed in the public finance literature. This paper gives an overview of this increasingly important area of international taxation, reviewing the key economic, legal, and practical concepts and issues bearing on the analysis and implementation of information exchange, and providing an account of recent policy initiatives and emerging theoretical insights.

Fiscal policy in the face of long-term expenditure uncertainties

A number of uncertainties about long-term expenditure commitments in industrial countries are examined: (i) the assumptions underlying the projections, (ii) the potential to further reduce non-age-related expenditures, (iii) the implicitly assumed absence of “shocks,” and (iv) the potential for raising revenue. This paper concludes that (i) there is scope, but within narrow limits, to reduce non-age-related expenditures; (ii) fiscal policy frameworks tend to understate risks; and (iii) prevailing tax rates leave little room for increasing taxation in the countries facing the strongest aging pressures. In sum, governments will have to adopt a much more ambitious fiscal policy stance to cope with aging populations. JEL Code H5 · H6     

Disentangling the Short and Long-Run Effects of Occupied Stock in the Rental Adjustment Process

In the current stand of literature on the rental adjustment process starting with Hendershott et al. (Real Estate Economics, 30, 165-183, 2002a, Journal of Real Estate Finance and Economics, 24, 59-87, 2002b) it has become practice to treat the compound variable “occupied stock” as a supply variable. In this study we show that this variable deserves a more critical investigation and that the general view of a supply variable may be misleading. Using panel data covering 30 urban areas for 17 years, we investigate the rental adjustment process in the German office market. The application of recently developed cointegration techniques for non-stationary panel data in conjunction with the corresponding error correction model (ECM) enables us to overcome the data limitations, particularly existent for most European real estate markets. Hence, our primary motivation is (a) to demonstrate how “occupied stock” should be interpreted correctly and (b) to provide useful insights into the long-term relationships and short-run dynamics of real office prime rents. The empirical evidence suggests that a one percent rise in office employment increases real rents on average by 1.64% through higher demand for office space. On the other hand, a one percent increase in the supply of office space decreases real rents in the long run by 2.25%. The results from the error correction model show that deviations from the long-run equilibrium lead to an adjustment process which restores equilibrium within approximately 3 years.     

Public Investment Criteria in Overlapping Generations Models of Open Economies

This paper derives criteria for worthwhile public investment in an overlapping generations model of an “almost small” open economy- an economy with access to external funding at a given interest rate, but with some influence over its temporal terms of trade. If the economy is dynamically efficient (i.e. the interest rate exceeds the growth rate), committed to free trade, public investment is debt financed and lump sum taxes are feasible, two results follow. First, the “social opportunity cost of public funds” will exceed the government's borrowing rate because of the adverse effect of government borrowing on the terms of trade. Second, the marginal rate of return on worthwhile public investment will be greater than the social opportunity cost of public funds if public and private investment are complements (substitutes) and the tax on capital is below (above) the rate that minimizes the steady state burden of servicing the debt.

Industrial Real Estate Investment: Does the Contrarian Strategy Work?

The superiority of the contrarian investment strategy, though well attested to in the finance literature, has received scant attention, if any, in the real estate literature. This study uses empirical industrial real estate investment return data from 1985Q1 to 2005Q3 for the US, and some Asia Pacific cities in order to ascertain the relative superiority of “value” and “growth” industrial real estate investments. The results show that “value” industrial property investment outperformed “growth” industrial property investment in all the holding periods under consideration. Furthermore the industrial property investments exhibit return reversal. This implies that the superiority of the contrarian strategy is sustainable. The results of stochastic dominance tests validate the relative superiority of “value” over “growth” industrial property investment. This implies that fund managers who traditionally have been favoring prime (i.e. growth) industrial property investment may have to reconsider their investment strategy if they want to maximize their return.     

The informal economy: Its role in post-industrial society

This article continues a line of argument, initiated in Futures¹, suggesting that a wide range of services which were once produced in the money economy are increasingly provided informally—on a self-service basis. The informal economy contains a diverse collection of activities that may be divided into three categories: the household, the communal, and the underground. This last in turn covers a wide range, from outright theft, to tax evasion and moonlighting. Government taxation and welfare policies, changes in lifestyles, and the self-service economy combine to make the informal economy a sector of growing importance. Governments have three options: they can ignore the informal economy, suppress it, or exploit it. The last appears preferable, but would require some initiatives from the state.     

Taxpayers' responsiveness to tax rate changes and implications for the cost of taxation in Sweden

Historically, labor supply elasticities have been used to evaluate tax policy and predict tax revenue effects. They are likely to underestimate taxpayers' response to tax rate changes, and hence to underestimate changes in potential tax revenues, however, because they measure only how taxpayers alter hours worked. Taxpayers can also respond to tax rate changes by altering, for instance, their work effort and form of compensation. An alternative measure that accounts for these responses as well as hours worked is the elasticity of taxable income. This paper estimates the elasticity of earned taxable income for Swedish taxpayers using two different approaches and a number of control variables and the 1990/1991 tax reform as a “natural experiment”. The preferred elasticity estimates fall in the range of 0.4–0.5, comparable with recent estimates for the U.S. and larger than most of the labor supply elasticity estimates used to evaluate tax policy in Scandinavia previously, which suggests that deadweight losses are two to three times higher than previously thought.

Poverty-decreasing indirect tax reforms: Evidence from Tunisia

This paper proposes a methodology to identify revenue-neutral directions for poverty-alleviating tax reforms. The search for such poverty-reducing tax reforms is done “robustly” over broad classes of poverty measures and poverty lines. The methodology, which is illustrated using data from Tunisia, is of significant policy interest given the widespread use of commodity subsidization and taxation in developing and developed countries alike. The results suggest that Tunisian poverty could be decreased robustly by following reform directions that are often at odds with frequently-heard views. They also highlight the importance of stating clearly under which set of ethical criteria the desirability of potential indirect tax reforms is assessed. JEL Code D12 ⋅ D63 ⋅ H53 ⋅ I32 ⋅ I38     

Determinants of tax evasion: A cross-country investigation

The purpose of this study is to expand on the work of Riahi-Belkaoiu [Riahi-Belkaoiu, A. (2004). Relationship between tax compliance internationally and selected determinants of tax morale. Journal of International Accounting, Auditing and Taxation, 13, 135-143] and systematically investigate, on a cross-country basis, many of the key determinants of tax evasion identified by Jackson and Milliron [Jackson, B. R., & Milliron, V. C. (1986). Tax compliance research: findings, problems and prospects. Journal of Accounting Literature, 5, 125-165]. Based on data for 45 countries, the results of the OLS regression analysis show that non-economic determinants have the strongest impact on tax evasion. Specifically, complexity is the most important determinant of tax evasion. Other important determinants of tax evasion are education, income source, fairness and tax morale. Overall, the regression results indicate that the lower the level of complexity and the higher the level of general education, services income source, fairness and tax morale, the lower is the level of tax evasion across countries. These findings remain robust to a broad range of cross-country control variables, an alternative tax evasion measure and various interactions.     

The makings of an information leader: the intraday price discovery process for individual stocks in the DJIA

The main purpose of this paper is to construct an intraday arbitrage price series for each stock in the DJIA using information in the Diamond Trust Fund ETF. We then compute the information shares (Hasbrouck in J Finan 50(4):1175–1199, 1995) for the actual versus the arbitrage prices for each stock. While previous literature documents that ETFs lead stock indices in information origination, we find that some firms are “information leaders” in that the information share that comes from the stock price is larger than that which comes from the ETF-related arbitrage price. Further analysis is conducted to uncover the firm-specific factors that are related to a stock’s role in information generation.     

Personal Taxation and Investment Incentives in a Small Open Economy

A simple portfolio model is used to investigate the effects of personal taxes on real investment incentives in a small open economy with large and small firms. When shares in large firms can be traded internationally and their rate of return is exogenously determined on international equity markets, a tax on the return on riskless bonds will induce a portfolio shift from bonds to shares in large firms. This shift reduces the impact of the bond tax on the required rate of return on shares in domestically owned small firms, provided that returns on shares in small and large firms are positively correlated. The total impact of the bond tax may even change from a negative to a counter-intuitive positive one if the “beta” between the returns on small and large firms is above unity. A personal tax on equity returns does in general have an ambiguous impact on the pre-tax rate of return requirement of domestically owned firms. An exogenous rate of return on large company shares is shown to enhance the possibility for the equity tax to reduce the required pre-tax rate of return in small domestic firms. A sufficient condition for a negative relationship is again that the “beta” between the returns in small and large firms is above unity.
