Small‐ and medium‐sized enterprises (SMEs) can play a crucial role in advancing environmental and social well‐being. Yet various—often conflicting—explanations have been offered to clarify why SMEs pursue sustainability. Some arguments foreground possibilities of profit maximization, whereas others emphasize individual values and convictions. Research supporting such contradicting explanations is often biased towards large enterprises or small, innovative frontrunners. In this article, we examine the underlying drivers of social and environmental interventions of SMEs by exploring empirical data from a survey of over 1,600 Canadian SMEs and complementary in‐depth interviews. We argue that sustainability actions of SMEs can be understood by viewing these firms as social actors—organizations that are shaped by individual values, internal and external interpersonal relationships, and are embedded in a social environment. This conceptualization directs attention to the full range of factors that shape sustainability engagement of SMEs and highlights frequently overlooked forms of sustainability‐oriented actions. 相似文献

We construct a monetary economy with aggregate liquidity shocks and heterogeneous idiosyncratic preference shocks. In this environment, not all agents are satiated at the zero lower bound (ZLB) even when the Friedman rule is the best interest‐rate policy the central bank can implement. As a consequence, central bank stabilization policy, which takes the form of repo arrangements in response to aggregate demand shocks, temporarily relaxes the liquidity constraint of impatient agents at the ZLB. Due to a pecuniary externality, this policy may have beneficial general equilibrium effects for patient agents even if they are unconstrained in their money balances. 相似文献

We derive a new Keynesian IS curve that is augmented to capture the direct effects of the labour share on output. Our derivation shows that the direct effect of the labour share on output is ambiguous. Furthermore, theory suggests that the expected labour share negatively affects output. Empirically, we find that the labour share plays a significant role in driving output dynamics. However contrary to theoretical expectation, the expected labour share positively affects output in some cases, a finding we call the ‘labour share puzzle’. We also find that over time, there seems to be a general shift in aggregate demand dynamics towards being profit-led, i.e. rising labour share decreases output. We conclude that policymakers should not ignore the labour share in their decisions. 相似文献

Prior empirical research suggests that consumers perceive pioneers as more prototypical (i.e., representative) of their product
categories than me-too followers. This prototypicality advantage is believed to contribute to an enduring marketplace advantage
for the pioneer. We extend research into pioneering prototypicality advantages by considering the ramifications of simultaneous
product design (i.e., product attribute) evolutions. We hypothesize that the simultaneous evolution of product designs of
both the pioneer and me-too will diminish the pioneer’s prototypicality advantage over the me-too, even though the me-too
does not initiate the change. To test our hypotheses, we create an experimental environment consisting of four cells, each
corresponding to a different marketplace scenario: a no-change condition; a simultaneous-evolution condition; a pioneer-updates-first
condition; and a leapfrogging (i.e., me-too updates first) condition. The results suggest that simultaneous design evolutions
can diminish the pioneer’s prototypicality advantage. As a result, me-too entry may be a more attractive strategy in the long-run
than currently believed in product categories characterized by substantial design evolution.

This research developed and tested machine learning models to predict significant credit card fraud in corporate systems using Sarbanes‐Oxley (SOX) reports, news reports of breaches and Fama‐French risk factors (FF). Exploratory analysis found that SOX information predicted several types of security breaches, with the strongest performance in predicting credit card fraud. A systematic tuning of hyperparamters for a suite of machine learning models, starting with a random forest, an extremely‐randomized forest, a random grid of gradient boosting machines (GBMs), a random grid of deep neural nets, a fixed grid of general linear models where assembled into two trained stacked ensemble models optimized for F1 performance; an ensemble that contained all the models, and an ensemble containing just the best performing model from each algorithm class. Tuned GBMs performed best under all conditions. Without FF, models yielded an AUC of 99.3% and closeness of the training and validation matrices confirm that the model is robust. The most important predictors were firm specific, as would be expected, since control weaknesses vary at the firm level. Audit firm fees were the most important non‐firm‐specific predictors. Adding FF to the model rendered perfect prediction (100%) in the trained confusion matrix and AUC of 99.8%. The most important predictors of credit card fraud were the FF coefficient for the High book‐to‐market ratio Minus Low factor. The second most influential variable was the year of reporting, and third most important was the Fama‐French 3‐factor model R2 – together these described most of the variance in credit card fraud occurrence. In all cases the four major SOX specific opinions rendered by auditors and the signed SOX report had little predictive influence. 相似文献

When agents are liquidity constrained, two options exist – sell assets or borrow. We compare the allocations arising in two economies: in one, agents can sell government (outside) bonds and in the other they can borrow by issuing (inside) bonds. All transactions are voluntary, implying no taxation or forced redemption of private debt. We show that any allocation in the economy with inside bonds can be replicated in the economy with outside bonds but that the converse is not true. However, the optimal policy in each economy makes the allocations equivalent. 相似文献

This paper focuses on the innovative actions of entrepreneurs, namely their tendency to reveal the intellectual capital that
results from their research efforts either in the form of public knowledge (publications) or private knowledge (patents).
Using data collected by the National Research Council within the US National Academies from their survey of firm’s that received
National Institutes of Health phase II Small Business Innovation Research awards between 1992 and 2001, we find that entrepreneurs
with academic backgrounds are more likely to publish their intellectual capital compared with entrepreneurs with business
backgrounds, who are more likely to patent their intellectual capital. We also find that, when universities are research partners,
their presence complements the tendencies of academic entrepreneurs but does not offset those of business entrepreneurs. 相似文献

Over the last few years, considerable attention has focused on aid fragmentation, the proliferation of donors and projects in developing countries. Aid fragmentation has continued to increase despite international efforts to foster donor coordination. One possible implication of fragmentation is smaller aid projects, potentially with the result of more administrative work for overtaxed recipient governments per dollar of aid received.This paper makes use of AidData data on bilateral aid commitments, sector, and funding agencies to explore the determinants of project size and to better understand the forces driving aid fragmentation. To the extent that project size is driven by the sectoral composition or purpose of aid, the associated administrative costs may be justified. Variations due to other factors, e.g. a donor’s administrative structure or bureaucratic interests, provide a stronger case for reforms. 相似文献
