The cluster robust variance estimator (CRVE) relies on the number of clusters being sufficiently large. Monte Carlo evidence suggests that the ‘rule of 42’ is not true for unbalanced clusters. Rejection frequencies are higher for datasets with 50 clusters proportional to US state populations than with 50 balanced clusters. Using critical values based on the wild cluster bootstrap performs much better. However, this procedure fails when a small number of clusters is treated. We explain why CRVE t statistics and the wild bootstrap fail in this case, study the ‘effective number’ of clusters and simulate placebo laws with dummy variable regressors.

This study investigates how supply chain sourcing strategies are associated with product quality recalls. In particular, the research examines how make-or-buy decisions (i.e., outsourcing), the use of foreign suppliers (i.e., offshore outsourcing), the relocation of production to offshore markets (i.e., offshoring), and decisions to consolidate supply bases (i.e., the use of few vs. myriad suppliers) are related to product recalls. Product recalls are serious quality failures in supply chains with significant, negative impacts on firm performance. Product recalls are frequently connected to the globalization of supply chains. Globalization has, at times, promoted inconsistency in quality control and standards, leading to quality problems and failures. Data across multiple industries, with widely reported recalls, have been collected and analyzed using regression techniques. Our findings indicate that offshore outsourcing has a greater impact on recalls than offshoring without outsourcing; outsourcing domestically has the least influence. Outsourcing to a smaller supplier base may lead to fewer recalls at low levels of outsourcing. However, it may exacerbate the impact of outsourcing on recalls at high levels of outsourcing. 相似文献

A vast literature has related perceptions of income inequality to individuals' income: the higher the level of income, the less inequality is perceived. Here, examining the perceptions of income and social inequality, we argue that rural or urban residence affects both inequality perceptions and the impact of income on these perceptions. We test the theory using survey data from 12 Central and Eastern European countries and we find that income negatively affects inequality perceptions but only in urban areas. These findings confirm the importance of accounting for urbanity to understand what drives individuals' perceptions of inequality. 相似文献

A number of recent economic modelling studies have attempted to analyse resource efficiency and the circular economy. However, modelling analysis in this area is relatively underdeveloped. In particular, many CGE models are unable to provide significant insight given their aggregated sectoral coverage. Here we describe the development of the Environmental Global Applied General Equilibrium (ENGAGE-materials) model created to consider the economic and sectoral effects of potential policies on a circular economy and resource efficiency, which affect materials and resources at the stages of extraction, production and recycling. Our policy scope is global with a special emphasis on China and Europe, as both regions have dedicated policies in place and indicate their willingness to take the lead. The case of steel is relevant as it is a key material for all economies across the world and offers a range of interesting features for circularity and sustainability. ENGAGE-materials models iron ore mining, primary production of iron and steel, secondary production of iron and steel, and steel scrap recycling at the global level. We utilise this technology rich framework to provide preliminary results on scenarios comprising economic insights into a saturation effect and straightforward policy such as doubling the availability of secondary steel. 相似文献

Drawing on the multi-principal–agent perspective, this research models the influence of venture capitalists' reputation for ethical behavior on entrepreneurs' willingness to partner decisions. We test our model using a two-study design. Study one, a conjoint experiment, revealed that explicit knowledge of past unethical behavior negatively affects entrepreneurs' willingness to partner. Interaction effects revealed that factors previously shown to influence the entrepreneurs' evaluations—investor value-add and investment track record—become largely contingent upon and often subjugated by investors' ethical reputation. Study two, a traditional between-subjects scenario experiment, revealed that when entrepreneurs develop their own perceptions about the ethicality of an investor's prior behaviors, the ethical dimension remains highly influential. Further, we find that as the consequences of rejecting funding become more severe (e.g., possible bankruptcy), entrepreneurs become increasingly willing to partner with unethical investors. We also find that high fear of failure entrepreneurs are less willing to partner with unethical investors than their low fear of failure counterparts. 相似文献

Devaluations and fiscal retrenchments coming from developed countries are buffeting less developed countries. Many emerging market countries have adopted inflation targeting as “best practice,” but now they are being advised to enhance their inflation targeting regimes with foreign exchange intervention. Here we use a DSGE model to tell some cautionary tales about this advice. A Taylor rule guides interest rate setting, while foreign exchange interventions are used as a second tool of monetary policy. These interventions are effective in our model since domestic and key currency bonds are imperfect substitutes. We derive optimal (Ramsey) intervention policies in response to foreign devaluations and fiscal retrenchments, and find that they are rather complex. So, we compare the optimal responses to policies that simply smooth real or nominal exchange rate movements. Our results suggest that discretion may be the better part of valor: pure inflation targeting may come closer to the optimal policy than exchange rate smoothing. A secondary result may also be of some interest: foreign exchange interventions have a stronger impact on inflation and output in an inflation targeting regime than do sterilized interventions; the Taylor rule augments the effects of a given intervention. 相似文献
