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.     

The effects of optimism bias in teams

This article imports a behavioural perspective into a team context to study the effort-coordination problem among agents. Specifically, we investigate how the presence of optimism bias impacts the severity of the free-rider problem, the organizational structure of the team and the compensation contracts offered to agents in equilibrium. The results indicate that all agents become more reluctant to exert effort and the team welfare decreases when some of its agents are optimistic, suggesting that optimism aggravates the free-rider problem in teams. Appointing a team leader makes all agents work harder, and the team benefits more by having the optimistic agent as its leader. These findings are in sharp contrast to the effects of overconfidence as identified in the literature. It is advisable to pay the optimistic agents less than the rational agents. Encouragingly, optimistic agents can learn about their own bias in the long run, leaving their team without too much detriment of optimism.     

The effects of small sample bias in Threshold Autoregressive models

This paper investigates Threshold Autoregressive (TAR) models that contain a limited number of observations in some regimes. Simulations show that within the context of the real exchange rate literature, parameter estimates exhibit significant small sample bias even with long time series data. These distortions create substantial power losses in attempting to identify values of coefficients from data.     

Explaining the nonlinear effects of financial development on economic growth

Using different indicators of financial development, recent empirical studies have discovered various patterns of nonlinearity in the relationship between financial development and economic growth. By adding consumption loans, which are nonproductive, into a standard model of asymmetric information, this paper generates a model that is able to replicate all possible nonlinear finance–growth relationships found in recent empirical studies.      

The Role of Market Sentiment in Asset Allocations and Stock Returns

Abstract

The authors investigate the role of mutual fund flows in incorporating market sentiment into asset prices. They show that retail investors adjust their investments among mutual fund categories in response to changes in market sentiment. Consistent with sentiment-induced price pressure through fund flows, they further find that firms favored by mutual funds, such as large-cap, dividend payers, and firms with high institutional ownership are sensitive to market sentiment. The authors construct a pricing factor representing sentiment risk and find that the sentiment factor is significant in standard asset pricing models and robust to various sorting procedure.

EDGAR on the internet: The welfare effects of wider information distribution in an experimental market for risky assets

Policies such as the SEC’s Fair Disclosure Rule, and technologies such as SEC EDGAR, aim to disseminate corporate disclosures to a wider audience of investors in risky assets. In this study, we adopt an experimental approach to measure whether this wider disclosure is beneficial to these investors. Price-clearing equilibrium models based on utility maximization and non-revealing and fully-revealing prices predict that in a pure exchange economy, an arbitrary trader would prefer that no investors are informed rather than all are informed; non-revealing theory further predicts that an arbitrary trader would prefer a situation in which all traders are informed rather than half the traders are informed. These predictions can be summarized as “None > All > Half”. A laboratory study was conducted to test these predictions. Where previous studies have largely focused on information dissemination and its effects on equilibrium price and insider profits, we focus instead on traders’ expected utility, as measured by their preferences for markets in which none, half, or all traders are informed. Our experimental result contradicts the prediction and indicates “Half > None > All”, i.e. subjects favor a situation where a random half is informed. The implication is that in addition to testing predictions of price equilibrium, experiments should also be used to verify analytical welfare predictions of expected utility under different policy choices.

The relevance and relative robustness of sources of inflation bias in Pakistan

We empirically examine the relevance and relative robustness of stabilization and non-stabilization sources of inflation bias for the typical discretionary monetary policy strategy of Pakistan. First, the stabilization and non-stabilization sources of inflation bias are identified, and their proxy variables are constructed. Second, a robustness evaluation strategy is developed based on bivariate and multivariate analysis of cointegrating relationships among inflation bias indicators and potential sources thereof to determine their long-term relevance and relative robustness or fragility. The stabilization sources of inflation bias such as exploitation of the inflation output trade-off for growth stimulation and the central bank’s preference for growth stabilization are the most relevant and relatively robust sources of inflation bias vis-à-vis the non-stabilization sources. Among the non-stabilization sources, only openness is partially relevant but is fragile.     

The value of information in asymmetric all-pay auctions

This note analyzes a two-player all-pay auction with incomplete information. More precisely, one bidder is uncertain about the size of the initial advantage of his rival modeled as a head start in the auction.I derive the unique Bayesian Nash equilibrium outcome for a large class of cumulative distribution functions of the head start. The stronger player generates an informational rent if and only if his head start distribution is not stochastically dominated by a uniform distribution. I identify why my results for an uncertain head start differ qualitatively from uncertainty about a cost function or a valuation.     

The value of information for auctioneers

An auctioneer wants to sell an indivisible object to one of multiple bidders, who have private information about their valuations of the object. A bidder's information structure determines the accuracy with which the bidder knows her private valuation. The main result of the paper is that the auctioneer's revenue is a convex function of bidders' information structures. One implication is that assigning asymmetric information structures instead of symmetric information structures to bidders is always revenue-enhancing. This paper generalizes a result of Bergemann and Pesendorfer [D. Bergemann, M. Pesendorfer, Information structures in optimal auctions, J. Econ. Theory 137 (2007) 580–609], who show that revenue-maximizing information structures are asymmetric.     

基于GJR—ALaplace方法的开放式基金风险研究

根据我国开放式基金收益率序列的尖峰、厚尾、有偏和波动时变的特征,引入非对gg,Laplace分布对收益率序列进行刻画和拟合。构建度量基金风险的动态GJR—Asymmetric～Laplace模型,在非对称Laplace分布、Laplace分布和正态分布三种分布假设下测算VaR,并做返回检验。选取12只开放式基金在2007．01．04～2009．12．31期间的日累计净值数据做实证研究。实证表明：除了基金大成债券外,其余11只基金显著通过假设,符合非对称Laplace分布,相rELaplace分布和正态分布来说,非对称Laplace分布能更好地拟合基金收益率序列。正态分布假设下风险度量值通过检验的基金数显著少于Laplace分布假设,而Laplace分布下通过检验的基金数亦少于非对称Laplace分布,可知非对称hplace分布假设下得出的基金动态风险值更为有效。     

A re-examination of international portfolio diversification based on evidence from leveraged bootstrap methods

This article investigates the issue of international portfolio diversification with respect to the three largest financial markets in the world—namely the US, Japan and the UK. In addition to making use of traditional portfolio analysis, we also suggest a procedure to calculate bootstrap correlation coefficients that can take into account the dynamic structure between the markets as measured by bootstrapped causality tests. Weekly data is used. The results from the first approach are supporting international diversification. The bootstrapped causality tests provide additional empirical support for this conclusion since the size of the causal effects is negligible and the bootstrap correlations are similar as the standard ones.     

Purchasing Power Parity and aggregation bias for a developing country: The case of Mexico

This paper investigates long-run Purchasing Power Parity (PPP) between the US and Mexico. We use a panel of disaggregated price data between the US and Mexico with a long time series to look at two types of aggregation bias. The first is examined in Imbs et al. — which we refer to as estimator aggregation bias — and the second is put forth by Broda and Weinstein — hereafter, data aggregation bias. The findings indicate substantial estimator aggregation bias and data aggregation bias. Although estimates using aggregate data and imposing homogeneous coefficients provide little evidence of PPP, findings with disaggregated data and heterogeneous coefficient estimators offer strong support. The results also suggest the presence of small-sample bias as examined in Chen and Engel, but with little effect on the qualitative results. Tradable goods and non-tradable goods show little distinction in convergence rates. Estimated half-lives are lower under flexible than fixed exchange rates and indicate rapid convergence during the Mexican peso crisis.     

The impact of fiscal-monetary policy interactions on government size and macroeconomic performance

This paper analyzes the relationship between inflation, output and government size by reexamining the time inconsistency of optimal monetary and fiscal policies in a general equilibrium model with staggered timing structure for the acquisition of nominal money à la Neiss (Neiss, Katharine S. (1999), Discretionary Inflation in a General Equilibrium Model, Journal of Money, Credit and Banking, 31(3), pp. 357–374.), and public expenditure financed by means of a distortive tax. It is shown that, with predetermined wages, the equilibrium rate of inflation is above the Friedman rule and the equilibrium tax rate is below the efficient level. In particular, the discretionary rate of inflation is nonmonotonically related to the natural output, positively related to government size, and negatively related to the degree of central bank conservatism. Finally, a regime with commitment leads to welfare improvements over a regime with discretion.     

Effects of Securities Transaction Taxes on Depth and Bid-Ask Spread

This note investigates the effects of introducing a transaction tax on depth and bid-ask spread using a static model where a competitive market maker faces informed and liquidity traders. When the degree of information asymmetry is low, an increase in the transaction tax can result into a smaller rise in the selling price and the depth may even increase in some cases. When information asymmetry is high, the dealer could increase the selling price more than the tax and sometimes lowers the depth. This can result in a market shutdown if the liquidity trader is driven out of the market. We thank Vincent Reinhart and Walter Fisher for helpful discussions. Special thanks are also due to an anonymous referee and the editor C.D. Aliprantis for insightful comments and suggestions which have helped us to improve the paper substantially.

The international effects of government spending composition

This paper incorporates a distinction between spending for government employment and spending for non-wage government consumption in a ‘new open economy macroeconomics’ model. Our results show that a permanent reduction in public employment in one country increases relative private consumption and appreciates the domestic exchange rate. We also compare announced reductions in domestic government employment and consumption, showing that these two policies have the same qualitative effects. When the reduction in public employment is used to finance increased government non-wage spending, the analytical results of the model are ambiguous, but a numerical analysis shows that relative consumption increases for a reasonable parameterization.     

The effects of labour unions on international capital tax competition

Abstract We analyze the impact of labour market rigidities on tax competition between two imperfectly integrated countries. Following a shift from a competitive to a unionized labour market in both countries, the capital tax can be adjusted upward in the country with the less rigid labour market, whereas the capital tax is always adjusted downward in the other country. Moreover, by reducing the labour cost differential between countries, trade liberalization gives rise to tax and welfare convergences. Finally, when a country adopts a flexible labour market, the unionized country may attract the majority of capital.
