Understanding Systematic Risk: A High-Frequency Approach

Based on a novel high-frequency data set for a large number of firms, I estimate the time-varying latent continuous and jump factors that explain individual stock returns. The factors are estimated using principal component analysis applied to a local volatility and jump covariance matrix. I find four stable continuous systematic factors, which can be well approximated by a market, oil, finance, and electricity portfolio, while there is only one stable jump market factor. The exposure of stocks to these risk factors and their explained variation is time-varying. The four continuous factors carry an intraday risk premium that reverses overnight.     

Relevance of Academic Research and Researchers' Role in the IASB's Financial Reporting Standard Setting

The International Accounting Standards Board (IASB) faces a vast number of standard‐setting issues at all levels of financial reporting. The purpose of this article is to explore the relevance of academic research for financial reporting standard setting and the role of academic researchers in the standard‐setting process. We contribute to the current debate surrounding International Financial Reporting Standards (IFRS) by drawing inferences from prior findings regarding the role of research in the IASB's standard‐setting efforts. After defining three broad categories of standard‐setting questions, we explore how the international heterogeneity of its constituency imposes constraints on the IASB's work. Then, whether and how academic research can inform policy makers is investigated from an epistemological perspective. Based on a review of extant literature, the general criteria which a piece of research should fulfil in order to be perceived as relevant and useful by standard setters are discussed. This discussion is followed by more detailed considerations regarding the suitability of different research approaches for each of the three categories of standard‐setting questions. We also touch on the subject of inferential problems inherent in most academic accounting research. Since the main objective is to contribute insights relevant to the IASB's efforts, we analyse academics' career systems and their incentives to engage in research intermediation, before discussing possible ways in which interested researchers can channel their insights into the IASB's standard‐setting process. Overall, the international dimension of IASB standard setting and its implications for relevant research are emphasized.     

Opening the Black Box: Internal Capital Markets and Managerial Power

We analyze the internal capital markets of a multinational conglomerate, using a unique panel data set of planned and actual allocations to business units and a survey of unit CEOs. Following cash windfalls, more powerful managers obtain larger allocations and increase investment substantially more than their less connected peers. We identify cash windfalls as a source of misallocation of capital, as more powerful managers overinvest and their units exhibit lower ex post performance and productivity. These findings contribute to our understanding of frictions in resource allocation within firms and point to an important channel through which power may lead to inefficiencies.     

Explaining nineteenth‐century bilateralism: economic and political determinants of the Cobden–Chevalier network1

This study investigates the empirical determinants of the treaty network of the 1860s and 1870s. It makes use of three central theories about the determinants of Preferential Trade Agreement (PTA) formation, considering economic fundamentals from neoclassical and ‘new’ trade theory, political‐economy variables, and international interaction due to trade diversion fears (dependence of later PTAs on former). These possible determinants are operationalized using a newly constructed dataset for bilateral cooperation and non‐cooperation among 13 European countries and the US. The results of logistic regression analysis show that the treaty network can be explained by a combination of ‘pure’ welfare‐oriented economic theory with political economy and international interaction models.     

TWO‐SIDED MARKETS WITH PECUNIARY AND PARTICIPATION EXTERNALITIES*

The existing literature on two‐sided markets addresses participation externalities, but it has neglected pecuniary externalities between platforms. In this paper we build a model that incorporates both externalities. In our set‐up, differentiated platforms compete in advertising levels and offer consumers a service free of charge that is financed through advertising. We show that advertising can exhibit the properties of a strategic substitute or complement. Surprisingly, we find that platform profits can increase with market entry and that there are cases in which the level of advertising rises with entry. We also consider endogenous entry and provide a welfare analysis.     

Predatory Trading

This paper studies predatory trading, trading that induces and/or exploits the need of other investors to reduce their positions. We show that if one trader needs to sell, others also sell and subsequently buy back the asset. This leads to price overshooting and a reduced liquidation value for the distressed trader. Hence, the market is illiquid when liquidity is most needed. Further, a trader profits from triggering another trader's crisis, and the crisis can spill over across traders and across markets.     

THE EFFECT OF GATE REVENUE SHARING ON SOCIAL WELFARE

This paper provides a theoretical model of a team sports league based on contest theory and studies the welfare effect of gate revenue sharing. It derives two counterintuitive results. First, it challenges the "invariance proposition" by showing that revenue sharing reduces competitive balance and thus produces a more unbalanced league. Second, the paper concludes that a lower degree of competitive balance compared with the noncooperative league equilibrium yields a higher level of social welfare and club profits. Combining both results, it concludes that gate revenue sharing increases social welfare and club profits in our model. ( JEL L83)     

Thinking about Prices versus Thinking about Returns in Financial Markets

Prices and returns are alternative ways to present information and to elicit expectations in financial markets. But do investors think of prices and returns in the same way? We present three studies in which subjects differ in the level of expertise, amount of information, and type of incentive scheme. The results are consistent across all studies: asking subjects to forecast returns as opposed to prices results in higher expectations, whereas showing them return charts rather than price charts results in lower expectations. Experience is not a useful remedy but cognitive reflection mitigates the impact of format changes.
