Through a qualitative study of two firms' supply networks, we develop a theory of the process by which environmental innovations emerge and proliferate in supply networks. To overcome limitations of current supply network innovation theories, which focus on the diffusion of existing innovations, we employ a complex adaptive systems perspective, which addresses how such innovations come into being in the first place and how they spread in a network over time. Our findings suggest a process model, in which temporally connected processes cross from the organizational to the network level, creating and spreading environmental innovations in supply networks. This model and its corresponding theoretical propositions were generated through an abductive research methodology. Our key insight is that development of environmental innovations in supply networks is an emergent phenomenon. Once in the network realm, the process ceases to be under the control of the dominant buying firm. Instead, self‐organization and decentralized coordination prevail.  相似文献

We study business cycle fluctuations in heterogeneous agent general equilibrium models featuring intensive and extensive margins of labor supply. A nonlinear mapping from time devoted to work to labor services generates operative extensive and intensive margins. Our model captures the salient features of the empirical distribution of hours worked, including how individuals transit within this distribution. We study how various specifications influence labor supply responses to aggregate technology shocks and find that abstracting from intensive margin adjustment can have large effects on the volatility of aggregate hours even if fluctuations along the intensive margin are small.  相似文献

This study examines managers’ use of discretion in determining goodwill impairment losses following the mandatory adoption of IFRS 3 “Business Combinations,” and whether this discretion reflects opportunistic reporting by managers or the provision of their private information. Although IFRS 3 was issued to improve the accounting treatment for goodwill and provide users with more useful and value‐relevant information regarding the underlying economic value of goodwill, it has been criticized on the grounds of the managerial discretion inherent in impairment testing. Therefore, ex‐ante, it is unclear how the impairment‐only approach has affected the reporting of goodwill impairment losses. After controlling for economic factors, empirical results reveal that managers are exercising discretion in the reporting of goodwill impairments following the adoption of IFRS 3. Specifically, goodwill impairments are more likely to be associated with recent CEO changes, income smoothing and “big bath” reporting behaviors. However, the results also indicate that goodwill impairments are strongly associated with effective governance mechanisms suggesting that managers are more likely to be exercising their accounting discretion to convey their private information about the underlying performance of the firm rather than acting opportunistically. These inferences are robust to various modeling specifications and variable definitions, suggesting that IFRS 3 has provided managers with a framework to reliably convey their private information about future cash flows consistent with the IASB's objectives in developing the impairment standard.  相似文献

The regulation of parallel trade is a fiercely debated issue in the global trading system. This paper investigates the welfare effects of parallel trade freedom for different levels of trade costs and market size. It is found that parallel trade freedom has a positive effect on global welfare if countries are sufficiently heterogeneous in terms of market size and trade costs are sufficiently low. Contrary to intuition, this result even holds in a situation where parallel trade freedom implies the closure of the smaller market. If, however, countries are virtually homogenous in terms of market size, parallel trade freedom may be detrimental to global welfare for specific levels of trade costs.  相似文献

This paper considers two integrated countries that differ only in their labour markets: one country hosts unions, whereas the other one pays competitive wages. These institutional differences are a source of comparative advantage, which crucially impact inter‐industry trade and welfare in the open economy. In this setting, deunionization exerts opposing welfare effects in the two economies. Increasing product market competition is beneficial for the unionized country and detrimental for its trading partner. Finally, we conduct an empirical analysis that provides strong support for the main hypotheses of our theoretical model.  相似文献

This study examines how variations in homicide rates in Mexico are associated with the likelihood of participating in cross‐border work, that is, living in Mexico but working in the U.S. Based on Mexican census data from 2000, 2010, and 2015, and information on homicides, a series of ordinary least squares models are estimated to analyze the relationship between cross‐border commuting and homicide rates at the individual level. Fixed effects models are also estimated to study this relationship at the municipal level. The results show that from 2000 to 2010 the increase in homicide rates in northern border municipalities in Mexico reduced the likelihood of being a cross‐border worker, while from 2010 to 2015 the decrease in the homicide rate increased the probability that workers engage in cross‐border work. The decline in the number of cross‐border workers is likely in part a result of the escalation in drug‐related violence that may have led them to change their country of residence.  相似文献

Abstract.  The current paper presents an empirical analysis of the current account positions during the pre Asian crisis period, in the four most crisis-hit countries (namely Thailand, the Philippines, South Korea and Indonesia). We have employed the procedures advocated by Husted for the presence of stationarity in current accounts by estimating a cointegration relationship between any country's exports and imports. The results do not substantiate the presence of cointegration between the series, implying that the macroeconomic fundamentals in these countries prior to the crisis were far from robust, at least from the perspective of current account sustainability.  相似文献

This article is inspired by real‐world phenomena that firms lose customers based on imprecise information and take a long time to recover. If consumers are playing an ordinary repeated game with fixed partners, there is no clear reason why recovery happens slowly. However, if consumers are playing an endogenously repeated game, a class of simple efficient equilibria exhibits the asymmetry of fast loss and slow recovery of customers after a bad signal. Exit is systematic, but formation of a new partnership is random. We also give empirical evidence of our equilibria at an individual‐firm level.  相似文献
