The Phillips curve under state-dependent pricing

We derive a Phillips curve equation from the dynamic stochastic general equilibrium (DSGE) model with state-dependent pricing developed by Dotsey et al. [1999. State-dependent pricing and the general equilibrium dynamics of money and output. Quarterly Journal of Economics 114, 655-690]. This state-dependent Phillips curve encompasses the new Keynesian Phillips curve (NKPC) based on Calvo-type price setting as a special case. We analyze the effect of the state-dependent terms (that is, the variations in the distributions of price vintages) on inflation persistence, and we examine whether the hybrid NKPC (that is, the NKPC extended by a lagged inflation term) can adequately describe inflation dynamics generated in a calibrated state-dependent pricing economy.

Half-time in the European Parliament—Expectations,reality, outlook

The European Parliament was set up by direct elections in June 1979. Great expectations had been placed in these direct elections with regard to the further development of the European Community. Now, half-way through the Parliament’s five-year term, a certain Euro-weariness is gaining ground. Had expectations been pitched too high? How is the work of the European Parliament so far to be assessed? What are the prospects for the future?     

Commercial bank behavior and monetary policy in an open economy : West Germany 1960–1980

This paper studies movements in the ratio of free liquid reserves of West German commercial banks to total deposits over the period 1960–1980. The desired ratio is assumed to depend positively on the ‘own yield’, measured by recently experienced variance of the required-reserve ratio (a proxy for portfolio adjustment costs avoided by holding free reserves), and negatively on the yield on alternative assets. The observed free reserve ratio also responds to changes in the Bundesbank's holdings of foreign exchange and net government deposits. Empirical tests on quarterly data support the hypothesis, though behavioral shifts occured in 1966 and 1973.     

“Just a Little Respect”: Effects of a Layoff Agent’s Actions on Employees’ Reactions to a Dismissal Notification Meeting

For several decades, most discussion on financial fraud has centered on the fraud triangle, which has evolved over time through various extensions and re-interpretations. While this has served the profession well, the articulation of the human side of the act is indirect and diffused. To address this limitation, this research develops a model to explain the role of human desires, intentions, and actions in indulgence of, or resistance to, the act of financial fraud. Evidence from religion, philosophy, sociology, neurology, behavioral economics, and social psychology is integrated to develop and support an alternative fraud model, called the disposition-based fraud model (DFM). To articulate the model, its two primary components, disposition and temptation, are further developed and extended. Although the DFM is generally applicable to any act of fraud, this paper focuses on executive fraud. The similarities and differences between the DFM and extant fraud models are discussed. Importantly, in light of the DFM, a re-interpretation of the fraud triangle is made to improve our understanding of the human element in it. Additionally, potential implications of the model for corporate governance are discussed, suggestions for further research are offered, and the DFM’s strengths and limitations are noted.     

Revisiting the role of the environment in the capabilities–financial performance relationship: A meta‐analysis

Within the capabilities‐based view of the firm, there is debate about the relative importance of ordinary and dynamic capabilities for firm performance and about the extent to which their performance effects are contingent on environmental conditions. We meta‐analyze 115 studies to investigate the relationship between both ordinary and dynamic capabilities and the financial performance of firms in relatively stable versus changing environments. The results suggest that the performance effects of both types of capabilities are positive and similar in magnitude. Environmental dynamism reinforces the effects of both ordinary and dynamic capabilities. Furthermore, the two types of capabilities are closely associated. Our findings provide support for a moderate capabilities‐based view of the firm, rather than one that considers dynamic capabilities as superior to ordinary ones.

The Illiquidity Discount of Life Insurance Investments

We incorporate an illiquid life insurance investment in the multi-period investment strategy of an investor with constant relative risk aversion and independent and identically distributed returns. In our setup, the liquid and the illiquid assets are risky and correlated and the illiquid investment cannot be rebalanced. We calculate the illiquidity discount as the difference in certainty equivalent rates of return between the optimal strategy with all assets being rebalanced in each period and the strategy with the illiquid investment. Calibrating our model to data of the German market we find a negative relationship between the level of risk aversion and the illiquidity discount when the investor does not rebalance at all. However, when the investor rebalances his liquid assets in each period to hedge against the illiquid investment the illiquidity discount becomes economically negligible.     

The Social Identity Approach to Effective Leadership: An Overview and Some Ideas on Cross-Cultural Generalizability

When employees identify with the groups and organizations they work for, this typically has positive implications for work-related attitudes and behaviors. The present paper provides a focused overview of the social identity approach to leadership and some ideas on its cross-cultural generalizability. To this end, we will first outline the basic tenets of the social identity approach and summarize the relations of organizational identification with work-related variables. Then, we will discuss the role of social identity-related concepts for effective leadership. In particular, we will present empirical studies on the following three aspects: (1) the transfer of leader identification onto their followers, (2) the role of leader prototypicality, and (3) the ways for leaders to actively manage the identities of the groups they lead. Finally, we will provide some suggestions on how to implement the principles of identity management into practice and offer suggestions for future research, with a special focus on China.
