Tax avoidance versus tax evasion: on some determinants of the shadow economy

In this paper we investigate how the possibility of (legal) tax avoidance affects the extent of (illegal) tax evasion and hence the shadow economy. We formulate a theoretical microeconomic model of household behavior in which households can participate in the official and in the shadow economy. Using comparative statics, we show that the complexity of the tax system affects participation in the shadow economy negatively, i.e. a more complex tax system with more possibilities of legal tax avoidance implies, ceteris paribus, a smaller labor supply in the shadow economy. In addition, we show that a reduction in the maximum admissible number of working hours in the official economy increases the labor supply in the shadow economy.     

Picking the winner? Empirical evidence on the targeting of R&D subsidies to start-ups

This paper investigates the allocation of R&D subsidies given to start-ups. Considering the coexistence of various R&D project schemes, we take an aggregate view and analyze the determinants of the receipt of (any) R&D subsidies within the first three business years of the start-ups. We argue that policymakers and funding authorities follow a strategy of ??picking the winner??. Analyzing start-ups in the East German state of Thuringia, we conduct logistic regressions and find ambiguous support. R&D subsidies are given to start-ups with innovative business ideas, especially academic spin-offs. Although the ambitions and patent stock of the founder(s) do not decide the receipt of R&D subsidies, team start-ups and the initial capital of a start-up tend to affect this decision positively. Hence, we cannot exclude a ??picking the winner?? strategy in targeting R&D subsidies to start-ups. More generally, however, the problems of policy targeting question the massive subsidization of private R&D.     

Fostering entrepreneurship in distressed urban neighbourhoods

During the last decade entrepreneurship research has focused increasingly on spatial aspects of entrepreneurship. Many systematic studies have been conducted on the national or regional scale, although other geographical scales—cities and their single districts and neighbourhoods—have drawn less attention. In this context, the paper aims, firstly, at identifying spatial success factors of entrepreneurial activities and their promotion at the local scale. Secondly, the paper aims at contributing to the development of a conceptual frame at the interface of entrepreneurship research, urban and economic geography, and regional economics. Empirically, the paper draws on results from explorative case studies in two distressed urban areas.     

Effect of the ban on short selling on market prices and volatility

We examine the effects of the short‐selling ban, imposed by Australian regulators in the wake of the global financial crisis, on the trading of financial stocks. Our findings argue against commonly stated reasons for imposing short‐sale bans. We find no evidence that short‐sale restrictions provide support for stock prices or that they reduce volatility. Moreover, stocks subject to the short‐selling ban suffered a severe degradation in market quality. Controlling for the adverse effects of the financial crisis on markets, we show that short‐selling restrictions increase intraday volatility, reduce trading activity and increase bid–ask spreads.     

On the cost of delayed currency fixing announcements

In Foreign Exchange Markets vanilla and barrier options are traded frequently. The market standard is a cutoff time of 10:00 a.m. in New York for the strike of vanillas and a knock-out event based on a continuously observed barrier in the inter bank market. However, many clients, particularly from Italy, prefer the cutoff and knock-out event to be based on the fixing published by the European Central Bank on the Reuters Page ECB37. These barrier options are called discretely monitored barrier options. While these options can be priced in several models by various techniques, the ECB source of the fixing causes two problems. First of all, it is not tradable, and secondly it is published with a delay of about 10–20 min. We examine here the effect of these problems on the hedge of those options and consequently suggest a cost based on the additional uncertainty encountered.      

Technology Strategies For Economic Development In A Fast Changing Global Economy

East Asian development experience provides the basis for understanding which are the essential elements of effective technology strategy and policy, those that are required for the efficacious development of countries that have not yet embarked on a path of sustained modernization. Globalization has had a profound impact on development, enabling countries that could exploit its propelling forces to pursue a potent strategy of export-led economic and technological development. The policies needed to sustain this strategy are those required to foster institutions that permit effective commerce among economic agents, those necessary to generate the rapid accumulation of human and physical capital, and those essential to ensure that resources are allocated in accord with the economy's dynamic comparative advantage. Of crucial importance among the latter are effectively implemented policies of selective intervention designed to develop infant industries and to foster their fast-paced achievement of international competitiveness through rapid attainment of the requisite technological capabilities.     

The performance of venture capital investments: Do investors overreact?

Using a unique proprietary data set of over 5400 realized and unrealized venture capital investments between 1980 and 2005, we examine the impact of demand-related factors, e.g. entrepreneurial activity, as well as supply-related factors, i.e. money provided by VC investors, on the return of individual VC investments. This way, we are able to shed more light on the question whether volatile VC investment returns are rather driven by fundamental changes with regard to the number of attractive investment opportunities or by the overreaction by investors. We find that rising demand for VC, i.e. an increase in entrepreneurial activity, results initially in higher returns. However, our results also indicate that overreaction on the supply side can be observed, destroying deal-level results. Overfunding, specifically overinvesting seems to be a recurring characteristic of the VC industry. In fact, contra-cyclical investment strategies yield highest deal-level returns.     

On the valuation of fader and discrete barrier options in Heston's stochastic volatility model

We focus on closed-form option pricing in Heston's stochastic volatility model, where closed-form formulas exist only for a few option types. Most of these closed-form solutions are constructed from characteristic functions. We follow this closed-form approach and derive multivariate characteristic functions depending on at least two spot values for different points in time. The derived characteristic functions are used as building blocks to set up (semi-) analytical pricing formulas for exotic options with payoffs depending on finitely many spot values such as fader options and discretely monitored barrier options. We compare our result with different numerical methods and examine the computational accuracy.     

Welche Rolle können Biokraftstoffe im Verkehrssektor spielen?

Biofuels have been the only alternative fuel which has substantially contributed to supplying transport with energy. Biofuels enjoyed broad support, but now they have come under criticism. In order to obtain answers to the question of what role biofuels could play in the future fuel mix, the following aspects are analysed: competing uses of scarce biomass and biofuels; sustainability of biofuels, standards and certification schemes; types and availability of biofuels; potentials for bioenergy and biofuels; and the technical compatibility of biofuels with vehicles. Finally, preconditions and necessary policy measures for the increased deployment of sustainable biofuels are examined.     

International Differences in Conditional Conservatism – The Role of Unconditional Conservatism and Income Smoothing

Abstract

Prior research documents that conditional conservatism, measured as the asymmetric timeliness of earnings reflecting bad vs. good news, varies with cross-country differences in institutional regimes. In this paper, we examine the determinants of conditional conservatism and related earnings attributes internationally. First, using panel data, we investigate whether competing earnings attributes such as unconditional conservatism and income smoothing affect conditional conservatism and its international differences. We find that these attributes are predictably correlated with conditional conservatism. Second, we address the question whether income smoothing and conditional conservatism are two fundamentally different earnings attributes. We show theoretically that both attributes yield different earnings distributions and that the motivations for producing earnings which possess these attributes differ. To test these predictions empirically, we calculate firm-specific time-series measures of asymmetric timeliness, using a novel trigonometric measure based on the standard Basu (1997)-type regression. Using this cross-sectional data, we test whether conditional conservatism and income smoothing are different and find them to be only weakly correlated for a broad international sample. Also, we demonstrate that income smoothing explains international differences in conditional conservatism. Finally, we estimate simple determinant models of conditional conservatism and income smoothing, showing that both earnings attributes are driven by different explanatory firm-level factors: Conditional conservatism increases with the importance of debt financing, while income smoothing increases with the importance of dividends. Despite some important limitations, we believe our results to be meaningful because they show that cross-country differences in conditional conservatism are influenced by the effects of other accounting properties, predominantly income smoothing. Especially, legal regime appears to drive income smoothing while losing its explanatory power for conditional conservatism when firm-specific factors are controlled for.
