Violence,Aggression, and Ethics: The Link Between Exposure to Human Violence and Unethical Behavior

Can exposure to media portrayals of human violence impact an individual’s ethical decision making at work? Ethical business failures can result in enormous financial losses to individuals, businesses, and society. We study how exposure to human violence—especially through media—can cause individuals to make less ethical decisions. We present three experiments, each showing a causal link between exposure to human violence and unethical business behavior, and show this relationship is mediated by an increase in individual hostility levels as a result of exposure to violence. Using observational data, we then provide evidence suggesting that this relationship extends beyond the context of our experiments, showing that companies headquartered in locations marked by greater human violence are more likely to fraudulently misstate their financial statements and exhibit more aggressive financial reporting. Combined, our results suggest that exposure to human violence has significant and real effects on an individual’s ethical decision making.     

The “Impossible Trinity” Hypothesis in an Era of Global Imbalances: Measurement and Testing

We outline new metrics for measuring the trilemma aspects: exchange rate flexibility, monetary independence, and capital account openness, taking into account substantial international reserve accumulation that has taken place since the 2000s. Since 1990, the trilemma variables in emerging markets have converged towards intermediate levels, characterizing by managed flexibility, using sizable international reserves as a buffer while retaining some degree of monetary autonomy. We test the linearity of the trilemma, and find that the weighted sum of the three trilemma variables adds up to a constant. Thus, a rise in one trilemma variable should be traded‐off with a drop of the weighted sum of the other two.     

An Evaluation of Friedman's Monetary Instability Hypothesis

In this article, I examine what I call Milton Friedman's Monetary Instability Hypothesis. Drawing on Friedman's work, I argue that there are two main components to this view. The first component is the idea that deviations between the public's demand for money and the supply of money are an important source of economic fluctuations. The second component of this view is that these deviations are primarily caused by fluctuations in the supply of money rather than the demand for money. Each of these components can be tested independently. To do so, I estimate an otherwise standard New Keynesian model, amended to include a money demand function consistent with Friedman's work and a money growth rule, for a period from 1875 to 1963. This structural model allows me to separately identify shocks to the money supply and shocks to money demand. I then use variance decompositions to assess the relative importance of shocks to the supply and demand for money. I find that shocks to the monetary base can account for up to 28% of the fluctuations in output whereas money demand shocks can account for less than 1% of such fluctuations. This provides support for Friedman's view.     

What Determines the Variability of Accounting Accruals?

The variability of accounting accruals provides a measure of the normal level of managers accounting discretion and has important implications for event studies of earnings management. We examine how this measure is related to the economic factors including both firm characteristics and attributes of the disclosure environment. We show that the variability of accruals is related to firm size, leverage, variability of cash flows, operating cycle, growth, and other factors. Significant industry differences and temporal patterns are also found.     

The mode of corporate diversification: Internal ventures versus acquisitions

This study investigates empirically the underlying motives for selecting the mode of corporate diversification and attempts to match the form of capital investments with a corresponding theoretical rationale for diversification. The empirical results seem to support both the transaction-costs rationale for diversification and the motive that arises from a firm's prior experience with each form of capital investment. However, the empirical findings are inconsistent with the explanation that is based on the owner-manager conflict of interest.     

Is Sound Just Noise?

We analyze the information content of the ambient noise level in the Chicago Board of Trade's 30-year Treasury Bond futures trading pit. Controlling for a variety of other variables, including lagged price changes, trading volumes, and news announcements, we find that the sound level conveys information which is highly economically and statistically significant. Specifically, changes in the sound level forecast changes in the cost of transacting. Following a rise in the sound level, prices become more volatile, depth declines, and information asymmetry increases. Our results offer important implications for the future of open outcry and floor-based trading mechanisms.     

Devaluation and liberalization in the presence of tariff and quota restrictions: An equilibrium model

The purpose of this paper is to examine and compare the effects of devaluation and trade liberalization policies on a monetary economy which uses quotas in contrast to an economy which uses tariffs. This is done in a general equilibrium framework. The paper also investigates the reasons for coupling liberalization policies with a devaluation.
