Firms developing new products often face the challenge of making investment decisions under uncertain input–cost conditions due to the price volatilities of the materials they use. These decisions need to be made long before the final products are launched on the market. Therefore, firms that invest in the opportunity to switch materials in a timely manner will have the flexibility to react to material price changes and realize competitive advantages. However, volatile material prices may also cause a firm to delay investment. Using real‐options reasoning, this paper studies the influence of input‐cost fluctuations on the timing decision to start new product development (NPD) and thus create the follow‐on opportunity to later replace an existing product. A model that combines waiting and switching options to derive influencing factors of the flexibility value that triggers the investment is developed and tested on a sample of material substitution projects from manufacturing firms. The results show how price uncertainty of the new and the old material, their joint price development, the expected project duration, and competitive preemption are related to the propensity to delay the start of NPD. The findings provide new insights on how timing in adopting materials can be used to hedge exposure to volatile material prices. The insights are relevant for adopters and producers of new materials, as well as for policy makers who strive for supporting the diffusion of new materials. 相似文献

Reducing tax system complexity is a common goal amongst policymakers; yet there is no commonly agreed definition of complexity. This paper seeks to fill this gap, by proposing the construction of an index of tax system complexity, conceived as a summary indicator of the overall complexity of a tax system at a particular point in time. If adopted, such an index would not only enable assessment of the changing level of a country's tax system complexity over time, but may also facilitate comparisons of the relative complexity of different countries' tax systems in future. 相似文献

This paper explores how informal information channels impact mutual fund performance. We measure the strengths of two location‐based information channels: 1) information transfers among fund managers (fund‐fund links) and 2) transfers between managers and the companies in which they invest (fund‐company links). We find that each channel increases investment performance in the absence of the other, but decreases it when acting in combination. Stock selection associated with the presence of one channel, but the absence of the other, earns positive future returns. Our results indicate that the economic benefits of informal information channels depend critically on the nature of their interactions. 相似文献

New Keynesian model in which households have Epstein–Zin preferences with time‐varying risk aversion and the central bank has a time‐varying inflation target can match the dynamics of nominal bond prices in the U.S. economy well. The model generates a large steady‐state term spread and its fitting errors for bond yields are comparable to those obtained from a nonstructural three‐factor model, and one‐third smaller than in models with a constant inflation target or risk aversion. Including data on interest rates has large effects on variance decompositions, making investment technology shocks much less important than found in other recent papers. 相似文献

We study the collapse of collusion in Québec's retail gasoline market following a Competition Bureau investigation, and show that it involved two empirical regularities: high margins, and asymmetric price adjustments. Using weekly, station‐level prices we test whether collusion was successful, and whether asymmetric adjustments were part of the cartel's strategy. We do so in the markets targeted by the investigation, and in markets throughout the province with similar pre‐collapse pricing (cyclical markets). Our results suggest that stations in both target and cyclical markets adjusted pricing following the announcement: margins fell (by 30%/15% in target/cyclical markets), and adjustments became more symmetric. 相似文献

This study extends current knowledge of upper echelon executive compensation beyond the CEO, specifically CFO compensation, based on whether they possess generalist or specialist skills. We find that “strategic” CFOs with an elite MBA (generalist) consistently command a compensation premium, while “accounting” CFOs (specialist) and CFOs with a non‐MBA master's degree, even from an elite institution, do not. Further, scarce “strategic” CFOs are awarded both higher salaries and higher equity‐based compensation. Our findings support the view that unique complementarities between scarce CFOs and firms increase these executives' bargaining power leading to pay premium. Our results are robust to post‐hiring years, firm sizes, board characteristics, and CFO's insider/outsider status. We contribute at the confluence of upper‐echelon compensation, executive human capital, resource‐based view, and assortative matching literatures. Copyright © 2014 John Wiley & Sons, Ltd. 相似文献

The attraction of foreign direct investment seeks, among other things, to increase the productivity of local companies through knowledge spillovers. However, the empirical evidence in this regard is contradictory. One influential factor is the absorptive capacity of the local companies. This article analyzes the effect of the presence of former employees of multinational corporations as employees of local companies, on the absorptive capacity of said companies. The study was done in Costa Rica, a country known for its successful strategy in the subject matter. The data come from a survey applied to 1167 companies by the Observatorio Costarricense de las Pymes in 2011. It was found that the hiring of former employees of multinational corporations by local companies has a positive effect on the index of absorptive capacity of companies in all productive sectors. Specifically, this hiring of former employees increases the index of absorptive capacity by nine percentage points, with differences by sector and the size of the company. 相似文献

While traditionally (Continental) Europe has not been known for an in particular debtor‐ or restructuring‐friendly insolvency practice, in recent decades, important reforms were implemented that would foster restructurings in Europe. In this article, we comparatively look a the status quo of insolvency and restructuring practice in five different European countries (Denmark, France, Germany, Netherlands, UK). We place our observations into the context of the preventive restructuring directive, to be implemented within the next two years after its publication on 26 June 2019. The directive leaves quite some room implementation, from a watered‐down restructuring tool with high access threshold to a pre‐insolvency debtor‐friendly US‐style restructuring procedure. 相似文献

We examine the impact of the introduction of VIX exchange‐traded products (ETPs) on the information content and pricing efficiency of VIX futures. We document that trades in VIX futures have become less informative and that pricing errors exhibit more persistence after the introduction of VIX ETPs. In addition, we observe that the price process of the VIX futures has become noisier over time. These findings suggest that the introduction of the VIX ETPs had a prominent effect on the properties and dynamics of the VIX futures. 相似文献

We study compensation contracts of individual portfolio managers using hand‐collected data of over 4,500 U.S. mutual funds. Variations in the compensation structures are broadly consistent with an optimal contracting equilibrium. The likelihood of explicit performance‐based incentives is positively correlated with the intensity of agency conflicts, as proxied by the advisor's clientele dispersion, its affiliations in the financial industry, and its ownership structure. Investor sophistication and the threat of dismissal in outsourced funds serve as substitutes for explicit performance‐based incentives. Finally, we find little evidence of differences in future performance associated with any particular compensation arrangement. 相似文献
