OPTIMAL CONSUMPTION AND INVESTMENT FOR A LARGE INVESTOR: AN INTENSITY‐BASED CONTROL FRAMEWORK

We introduce a new stochastic control framework where in addition to controlling the local coefficients of a jump‐diffusion process, it is also possible to control the intensity of switching from one state of the environment to the other. Building upon this framework, we develop a large investor model for optimal consumption and investment that generalizes the regime‐switching approach of Bäuerle and Rieder (2004) .     

How barriers to international trade affect TFP

We ask how barriers to international trade affect TFP when there are monopoly rights in the import-competing industries. Holmes and Schmitz [1995. Resistance to new technology and trade between areas. Federal Reserve Bank of Minneapolis Quarterly Review 19, 2–17] show that without barriers to trade TFP in these industries is as large as possible. We study the general case of finite barriers to trade. We find that binding quotas lead to the use of inefficient technology in the import-competing industries. In addition, finite quotas or tariffs imply that the import-competing industries produce larger than efficient quantities, if they produce at all. For both of these reasons, barriers to international trade reduce TFP.     

Brand portfolio, corporate image, and reputation: Managing brand deletions

Brand portfolio management addresses, among other issues, the interrelated questions of what brands to add, retain, or delete. A small number of brands in a firm’s brand portfolio can often have a disproportionately large positive or negative impact on its image and reputation and the responses of stakeholders. Brand deletions can be critical from the standpoint of a firm being able to free up resources to redeploy toward enhancing the competitive standing and financial performance of brands in its portfolio with the greatest potential to positively affect its image and reputation. Against this backdrop, the authors focus on the organizational and environmental drivers of brand deletion propensity, the predisposition of a firm to delete a particular brand from its brand portfolio. The authors propose a conceptual model delineating the drivers of brand deletion propensity and suggest directions for future research, including the related concept of brand deletion intensity.

Are Higher Education Subsidies Second Best?

An optimal taxation framework is considered in which part of the population can take advantage of investment in higher education. It is shown that social welfare can sometimes be increased by supplementing linear income taxes with a subsidy to material investment in higher education, but that social welfare can never be increased by supplementing a non‐linear income tax with such a subsidy.     

BARRIERS TO ENTRY AND DEVELOPMENT*

We ask whether barriers to entry are a quantitatively important reason for the income gap between developing countries and the United States. We develop a tractable general equilibrium model that captures the effects of barriers to entry and the other main distortions typically considered in the development literature. We carry our model to the data and ask it to match the main development facts from the Penn World Table. We find that this requires large barriers to entry in developing countries, which account for about half of the income gap with the United States.     

A note on public debt, tax-exempt bonds, and Ponzi games

By issuing tax-exempt bonds, the government can incur debt and never pay back any principal or interest, even if the economy without public debt evolves on a dynamically efficient growth path. The welfare effects of such a Ponzi type borrowing scheme are mixed. The current young will unambiguously benefit. Depending on preferences and the aggregate technology, a finite number of subsequent generations may also benefit. However, the welfare of all generations thereafter will be lower than in the economy without public debt.     

Controllability and Persistence of Money Market Rates along the Yield Curve: Evidence from the Euro Area

Abstract. Controllability of longer‐term interest rates requires that the persistence of their deviations from the central bank's policy rate (i.e. the policy spreads) remains sufficiently low. This paper applies fractional integration techniques to assess the persistence of policy spreads of euro area money market rates along the yield curve. Independently from anticipated policy rate changes, there is strong evidence for all maturities that policy spreads exhibit long memory. We show that recent changes in the operational framework and the communication strategy of the European Central Bank (ECB) have significantly decreased the persistence of euro area policy spreads and, thus, have enhanced the ECB's influence on longer‐term money market rates.     

Organizational adaptation to disruptions in the natural environment: The case of climate change

Dynamic and intensified changes in the global ecosystem result in significant disruptions to the natural environment. One of the most prominent examples of this is climate change and the resulting natural disasters. As firms are embedded within the natural environment, they need to adapt to any environmental disruptions that transpire. Using Swiss and Austrian electric utilities as case studies, this paper empirically explores the underlying organizational capabilities necessary to enable adaptation to climate-related disruptions to a firm's resource supply, production processes, and product distribution. Through a case- and literature-based iterative process of analytical induction, three organizational capabilities are derived: climate knowledge absorption as an essential information generating and internalizing capability, climate-related operational flexibility as a short-term adjustment capability, and strategic climate integration as a long-term, innovation-focused capability.
