Static versus dynamic hedges: an empirical comparison for barrier options

We conduct an empirical comparison of static versus dynamic hedges of barrier options. Using more than five years of data, we compare a number of static hedges from the literature with dynamic hedges based on the local volatility model. The main result is that the variability of profit-and-loss distributions from certain static hedges is significantly smaller than that of dynamic hedges and robust to changing market scenarios. Furthermore, these static hedges are able to provide a robust tracking of barrier options’ sensitivities.

Australia's consumption‐based greenhouse gas emissions

We use data from the World Input‐Output Database in a multiregional input–output model to analyse Australian consumption‐based greenhouse gas emissions for the years 1995 to 2009. We find that the emission content of Australian macroeconomic activity has changed over the 15‐year period. Consumption‐based emissions have been growing faster than production‐based emissions since 2001. We show that emissions embodied in Australian imports are increasingly becoming a significant source of emissions. We investigate emissions in Australian imports and find that increased trade with China contributed substantially to the increase in Australia's consumption emissions. China was the largest exporter of emissions to Australia and accounted for almost half of emissions embodied in Australian imports since 2002. The growth of trade with China coincides with the increase in imported emissions as well as the increase in aggregate consumption emissions. Our results suggest that tracking consumption emissions together with production emissions provides a more complete picture of Australian emissions.     

Increasing the Number of Women on Boards: The Role of Actors and Processes

In this article, we offer an approach of how participative stakeholder innovation can be evaluated in complex multistakeholder settings that address wicked issues. Based on the principle of mutual value creation, we present an evaluation framework that accounts for the social interaction process during which stakeholders integrate their resources and capabilities to develop innovative products and services. To assess this evaluation framework, we collected multiple data from the case study of the Swiss Cardiovascular Network, which represents a multistakeholder setting related to the prevention of cardiovascular disease. Our findings indicate that the evaluation dimensions of the stakeholders’ mindsets, the process and context of the stakeholder interactions, as well as the outcomes are useful concepts to account for a cooperative process of innovation in a multistakeholder setting. We discuss both the theoretical and practical insights of our analysis for participative stakeholder innovation.     

Women Directors on Corporate Boards: From Tokenism to Critical Mass

Academic debate on the strategic importance of women corporate directors is widely recognized and still open. However, most corporate boards have only one woman director or a small minority of women directors. Therefore they can still be considered as tokens. This article addresses the following question: does an increased number of women corporate boards result in a build up of critical mass that substantially contributes to firm innovation? The aim is to test if ‘at least three women’ could constitute the desired critical mass by identifying different minorities of women directors (one woman, two women and at least three women). Tests are conducted on a sample of 317 Norwegian firms. The results suggest that attaining critical mass – going from one or two women (a few tokens) to at least three women (consistent minority) – makes it possible to enhance the level of firm innovation. Moreover, the results show that the relationship between the critical mass of women directors and the level of firm innovation is mediated by board strategic tasks. Implications for both theory and practice, and future research directions are discussed.     

The mechanics of a graceful exit: Interest on reserves and segmentation in the federal funds market

To combat the financial crisis that intensified in the fall of 2008, the Federal Reserve injected a substantial amount of liquidity into the banking system. The resulting increase in reserve balances exerted downward price pressure in the federal funds market, and the effective federal funds rate began to deviate from the target rate set by the Federal Open Market Committee. In response, the Federal Reserve revised its operational framework for implementing monetary policy and began to pay interest on reserve balances in an attempt to provide a floor for the federal funds rate. Nevertheless, following the policy change, the effective federal funds rate remained below not only the target but also the rate paid on reserve balances. We develop a model to explain this phenomenon and use data from the federal funds market to evaluate it empirically. In turn, we show how successful the Federal Reserve may be in raising the federal funds rate even in an environment with substantial reserve balances.     

Are you a collaborative leader?

Social media and technologies have put connectivity on steroids and made collaboration more integral to business than ever. But without the right leadership, collaboration can go astray. Employees who try to collaborate on everything may wind up stuck in endless meetings, struggling to reach agreement. On the other side of the coin, executives who came of age during the heyday of "command and control" management can have trouble adjusting their style to fit the new realities. In their research on top-performing CEOs, Insead professors Ibarra and Hansen have examined what it takes to be a collaborative leader. They've found that it requires connecting people and ideas outside an organization to those inside it, leveraging diverse talent, modeling collaborative behavior at the top, and showing a strong hand to keep teams from getting mired in debate. In this article, they describe tactics that executives from Akamai, GE, Reckitt Benckiser, and other firms use in those four areas and how they foster high-performance collaborative cultures in their organizations.     

International Procurement as a Signal of Export Quality

In 1996, the British Government was accused of a protectionist 'buy British' campaign when it awarded a contract for army ambulances to Land Rover. We present a model where the procurement decision of the government affects the perception of consumers in the rest of the world about the quality of the domestic firm's product relative to that of a foreign rival's product. The model compares the outcome when the government's only concern is value for money with the outcome when the government takes account of the effect of its decision on export sales of the domestic firm.     

How task constraints affect inspiration search strategies

Searching for sources of inspiration is central to creative design; however, we have limited knowledge of individual inspiration search strategies in response to varying levels of task constraints. We studied 39 high-school students’ inspiration search strategies using Google Images. Low task constrainedness led to divergent search marked by quick iterations, limited design task usage, and a heterogeneous image set. Intermediate constrainedness prompted in-depth, on-task exploration characterized by slow and careful iterations with more search result examination, extensive design task usage, and homogenous images. High constrainedness led to flexible bracketing with quick, flexible design task use, ending with heterogeneous images. Images from the intermediately and highly constrained conditions generated more ideas and were perceived as more inspiring (relative to low) in a new group of students. We discuss the idea of a ‘sweet spot’ of constrainedness in an inspiration search process in design and consider implications for design research and future work.     

The value of local political connections in a low-corruption environment

We use exogenous changes in Danish local municipality sizes to identify a large positive effect of political power on the profitability of firms related by family to local politicians. Our difference-in-differences estimate is consistent with a unitary elasticity of connected firms’ performance to political power (as measured by population per elected politician). Increasing power boosts firms’ operating returns, especially in industries relying heavily on public demand. Focusing on arguably the world's least corrupt country, we highlight the importance of corporate rent seeking at local governmental levels, which account for nearly half of total public expenditures.
