Abstract
Prior studies of real-activity earnings management (REM) focus on earnings-inflating abnormal activities. We seek to establish the existence of downward REM by investigating several corporate events in which managers have incentives to temporarily deflate market valuations. Specifically, we focus on, and find downward REM before, share repurchases, management buyouts (MBOs), and CEO option awards. Large-sample evidence of downward REM is also found in our general analysis of earnings smoothing. Downward REM becomes much smaller or nonexistent when there is a lack of managerial incentives in those events, such as non-carry-through repurchases, incomplete MBOs, and unexpected option awards. Following the research design of Zang, we find that various REM and accrual-based earnings management (AEM) cost factors consistently influence the magnitude of downward REM and AEM around the three corporate events.

The Diablo 3 Economy: An Agent Based Approach

Computational Economics,
No. 2,
2016
Abstract
Designers of MMOs such as Diablo 3 face economic problems much like policy makers in the real world, e.g. inflation and distributional issues. Solving economic problems through regular updates (patches) became as important to those games as traditional gameplay issues. In this paper we provide an agent framework inspired by the economic features of Diablo 3 and analyze the effect of monetary policy in the game. Our model reproduces a number of features known from the Diablo 3 economy such as a heterogeneous price development, driven almost exclusively by goods of high quality, a highly unequal wealth distribution and strongly decreasing economic mobility. The basic framework presented in this paper is meant as a stepping stone to further research, where our evidence is used to deepen our understanding of the real-world counterparts of such problems. The advantage of our model is that it combines simplicity that is inherent to model economies with a similarly simple observable counterpart (namely the game environment where real agents interact). By matching the dynamics of the game economy we can thus easily verify that our behavioral assumptions are good approximations to reality.

Transition to Clean Technology
Daron Acemoglu, Ufuk Akcigit, Douglas Hanley, William R. Kerr
Journal of Political Economy,
No. 1,
2016
Abstract
We develop an endogenous growth model in which clean and dirty technologies compete in production. Research can be directed to either technology. If dirty technologies are more advanced, the transition to clean technology can be difficult. Carbon taxes and research subsidies may encourage production and innovation in clean technologies, though the transition will typically be slow. We estimate the model using microdata from the US energy sector. We then characterize the optimal policy path that heavily relies on both subsidies and taxes. Finally, we evaluate various alternative policies. Relying only on carbon taxes or delaying intervention has significant welfare costs.

Networks and the Macroeconomy: An Empirical Exploration
Daron Acemoglu, Ufuk Akcigit, William R. Kerr
NBER Macroeconomics Annual,
2015
Abstract
How small shocks are amplified and propagated through the economy to cause sizable fluctuations is at the heart of much macroeconomic research. Potential mechanisms that have been proposed range from investment and capital accumulation responses in real business-cycle models (e.g., Kydland and Prescott 1982) to Keynesian multipliers (e.g., Diamond 1982; Kiyotaki 1988; Blanchard and Kiyotaki 1987; Hall 2009; Christiano, Eichenbaum, and Rebelo 2011); to credit market frictions facing firms, households, or banks (e.g., Bernanke and Gertler 1989; Kiyotaki and Moore 1997; Guerrieri and Lorenzoni 2012; Mian, Rao, and Sufi 2013); to the role of real and nominal rigidities and their interplay (Ball and Romer 1990); and to the consequences of (potentially inappropriate or constrained) monetary policy (e.g., Friedman and Schwartz 1971; Eggertsson and Woodford 2003; Farhi and Werning 2013).

Types of Cooperation Partners as Determinants of Innovation Failures
Walter Hyll, Gunnar Pippel
Technology Analysis and Strategic Management,
No. 4,
2016
Abstract
In this paper we analyse if specific R&D cooperation partners are related to an increase in the probability of innovation failures in terms discontinuing innovation projects. We distinguish between seven different R&D cooperation partner types, and we discriminate between product innovation failures and process innovation failures. Using German Community Innovation Survey data we find that, firstly, each type of R&D cooperation partner has a different effect on innovation failures. Secondly, we show that product innovation failures and process innovation failures are not affected in equal measure by the same type of R&D cooperation partner. Our results suggest that while R&D cooperation with public research institutes is significantly and negatively related to the probability to cancel a process innovation project, the coefficient is positive but insignificant for product innovation failures. Firms conducting partnerships with suppliers, however, run the risk of both product and process innovation failures. In turn, cooperation with competitors is positively correlated only to process innovation failures.

Im Fokus: Industrielle Kerne in Ostdeutschland und wie es dort heute aussieht – Das Beispiel des Chemiestandorts Bitterfeld-Wolfen
Gerhard Heimpold
Wirtschaft im Wandel,
No. 6,
2015
Abstract
Der Erhalt industrieller Kerne war eines der wirtschaftspolitischen Ziele beim Aufbau Ost. Einer dieser Kerne ist der Chemiestandort Bitterfeld-Wolfen in Sachsen-Anhalt. Der Beitrag untersucht, wie es nach 25 Jahren Deutscher Einheit um diesen industriellen Kern bestellt ist. In einem Satz: Der Kern ist nicht mehr der alte. Die Kombinate der Großchemie waren als Ganzes nicht privatisierbar. An ihre Stelle sind moderne mittelständische Chemiebetriebe getreten. Daneben haben sich neue Branchen, etwa die Glasindustrie, angesiedelt, und in Gestalt einer attraktiven Seenlandschaft ist aus den Braunkohlentagebauen etwas völlig Neues entstanden. Bei den Forschungsaktivitäten kann die Region aber mit westdeutschen Verhältnissen nicht mithalten. Die vielleicht größte künftige Herausforderung wird in einer demographisch bedingt rückläufigen Erwerbspersonenzahl liegen.

A Review of Empirical Research on the Design and Impact of Regulation in the Banking Sector
Sanja Jakovljević, Hans Degryse, Steven Ongena
Annual Review of Financial Economics,
2015
Abstract
We review existing empirical research on the design and impact of regulation in the banking sector. The impact of each individual piece of regulation may inexorably depend on the set of regulations already in place, the characteristics of the banks involved (from their size or ownership structure to operational idiosyncrasies in terms of capitalization levels or risk-taking behavior), and the institutional development of the country where the regulation is introduced. This complexity is challenging for the econometrician, who relies either on single-country data to identify challenges for regulation or on cross-country data to assess the overall effects of regulation. It is also troubling for the policy maker, who has to optimally design regulation to avoid any unintended consequences, especially those that vary over the credit cycle such as the currently developing macroprudential frameworks.

Political lendings of German Savings Banks
A recent paper of the Halle Institute for Economic Research (IWH) suggests that German local politicians take advantage of their influence on the credit decisions of German savings banks. “German savings banks on average increase the supply of commercial loans by €7.6 million in the year of a local election”, says IWH president Reint E. Gropp. Loans that the savings banks generate during election years also perform worse and lead to lower interest income. The results suggest that local politicians take advantage of savings banks to further their chances of re-election.
