The rise of Mexican entrepreneurial migration to the United States: A mixed‐embeddedness approach

Although many studies have analyzed the behavior of high‐skilled migration to the United States, few have focused on the escalating migration of Mexican entrepreneurs, and particularly on the determinants of this kind of high‐skilled migration. This article addresses this gap through a qualitative approach conforming to quantitative procedures, based on 20 in‐depth interviews applied to Mexican entrepreneurs working and/or living in the United States. Theoretically, a mixed‐embeddedness approach guides this research because it allows examining both the individual characteristics of Mexican entrepreneurs, and the influence of the home and host countries' institutional contexts on their business endeavors. Findings revealed Mexico's institutional weaknesses, such as insecurity, corruption, and bureaucracy, are important drivers of migration but so are the perception of a friendly U.S. fiscal system, the search for a better quality of life, and the appeal of a more transparent business environment.     

中国国有企业改革：经验、困境与出路*

作为国有企业产权改革主要模式，“混合所有制”改革是否有助于确保国有资产保值增值，是否有助于推动中国经济可持续发展等问题仍存在探讨空间。本文基于对于改革开放以来中国国有企业改革的成就和教训的考察，指出“混合所有制”可以作为竞争性部门国有企业改革的一个过渡形式；对于垄断央企的改革应该充分借鉴国际上自然垄断行业的改革经验，打破行政垄断，推动竞争性框架建立，并切实实现从“管企业”逐步调整为“管资本”，通过改革实现国有资产的保值增值，并为经济创造新的增长点。     

Attitudes,norms and difficulties underlying road sharing intentions as drivers and cyclists: Evidence from the Czech Republic

Cycling-inclusive urban planning is attracting attention worldwide because of the environmental, health, economic, and transport benefits inherent to cycling from the individual and the societal perspectives. The Czech Republic is one of the emerging cycling countries that are trying to promote and support cycling, but cycling mode shares are low because of the poor quality of the scarce infrastructure and the psychological barrier of the perceived lack of safety when cycling in mixed traffic. This study takes a multimodal approach based on the Theory of Planned Behaviour and focuses on the factors underlying the willingness to share the road from the perspective of cyclists and drivers: positive attitudes toward cycling, positive attitudes toward cyclists’ behavior, social norms toward cycling and anxiety to share the road. A web-based questionnaire was tailor-designed and administered in the Czech Republic via social networks, web forums, and the Civinet network, and a hybrid bivariate-ordered model tested the behavioral framework. Results show that the willingness to share the road as a cyclist or as a driver relates positively to positive attitudes towards cycling and cyclists’ behavior, and negatively to the anxiety of sharing the road. Moreover, mediator effects are observed and a clear relation emerges between the experience on the road as both a cyclist and a driver on the willingness to share the road as a cyclist. Lastly, results show that the factors underlying road sharing intentions are related significantly to gender, travel habits, and perceived personal and infrastructure-related barriers to cycling.     

Measuring the effectiveness of US monetary policy during the COVID-19 recession

The COVID-19 recession that started in March 2020 led to an unprecedented decline in economic activity across the globe. To fight this recession, policy makers in central banks engaged in expansionary monetary policy. This paper asks whether the measures adopted by the US Federal Reserve (Fed) have been effective in boosting real activity and calming financial markets. To measure these effects at high frequencies, we propose a novel mixed frequency vector autoregressive (MF-VAR) model. This model allows us to combine weekly and monthly information within a unified framework. Our model combines a set of macroeconomic aggregates such as industrial production, unemployment rates, and inflation with high-frequency information from financial markets such as stock prices, interest rate spreads, and weekly information on the Fed's balance sheet size. The latter set of high-frequency time series is used to dynamically interpolate the monthly time series to obtain weekly macroeconomic measures. We use this setup to simulate counterfactuals in absence of monetary stimulus. The results show that the monetary expansion caused higher output growth and stock market returns, more favorable long-term financing conditions and a depreciation of the US dollar compared with a no-policy benchmark scenario.     

混合股权制衡度与真实盈余管理行为

混合所有制改革形成了非国有股与国有股相互制衡的股权结构。通过研究国有企业中非国有股权和国有股权相互制衡的程度与真实盈余管理行为的关系发现：混合股权制衡度显著抑制了国有企业的真实盈余管理行为，但当国有性质股权占比小于非国有性质股权占比时上述抑制作用减弱。另外,参与混合所有制改革的金融类、外资类股权相比民营类股权制衡度，对真实盈余管理行为发挥了更显著的治理作用。机制检验发现，混合股权制衡一方面通过提升业绩，提高对真实盈余管理动机的抑制作用，从而缓解了真实盈余管理行为；另一方面通过提升内部控制对真实盈余管理的抑制作用，降低了真实盈余管理行为。以上结论有助于深化国有企业混合所有制改革，为提升混改中的审计监管质量提供参考。     

我国互联网金融消费者权益保护体系建设与优化路径

互联网金融作为互联网技术与传统金融融合后的新兴业态模式,具有降低交易双方成本,提升金融服务效率和便捷性的作用,在满足了个性化金融服务需求的同时,还促进了我国普惠金融发展。但随着互联网金融模式的不断丰富,互联网金融混业经营及脱媒现象加剧,在缺乏监管和法律定位不明的情况下,互联网金融给消费者带来诸多潜在风险。对此,需要按照时间发展顺序,在短期内强化互联网金融消费者权益保护相关政策措施,保证互联网金融市场平稳发展;中长期则注重互联网金融发展质量,通过不断完善互联网金融消费者权益保护机制,进而构建具有综合性特征的互联网金融消费者权益保护体系。     

混合所有制改革是否有助于缓解人力资本配置扭曲

将人力资本在所有制企业间的配置扭曲（错配）理解为技术配置扭曲和规模配置扭曲两个方面，基于1998—2013年中国工业企业数据库的相关数据，探讨国有企业混合所有制改革影响人力资本配置扭曲的内生机理，结果表明：混合所有制改革鼓励非国有资本通过参股、控股和并购等方式参与到国有企业的生产决策中，这有助于完善国有企业的公司治理结构和利润分配机制，进一步缓解人力资本的技术配置扭曲和规模配置扭曲程度；相对于非行政垄断行业，行政垄断行业中国有企业混合所有制改革对于人力资本配置扭曲的缓解作用较小。     

Bertrand versus Cournot competition in a downstream mixed oligopoly with foreign ownership

Focusing on foreign ownership in the private firm, we examine the Cournot-Bertrand comparison in a mixed oligopolistic market with vertical market structure. We have found that if public and private firms were charged with uniform price for their inputs, then Cournot-Bertrand ranking in market outcomes confirms those obtained by Ghosh and Mitra (2010). This implies that under uniform pricing in the upstream sector, the vertical market structure does not have substantial influences on Cournot-Bertrand ranking. However, if discriminatory pricing is adopted, firm's profits, output, and social welfare are often reversed to those obtained from uniform pricing in the upstream sector. Given the closeness of products, if the share of foreign ownership is sufficiently low, social welfare in Cournot competition can exceed that of Bertrand competition, contrasting with the standard welfare ranking that Bertrand welfare is strictly higher than Cournot. This implies that Cournot competition can be more socially desirable than Bertrand in mixed oligopoly with vertical market structure if discriminatory pricing scheme is adopted by foreign upstream monopolists.     

Optimal privatization policy with asymmetry among private firms

We revisit the relationship between the optimal privatization policy and market competition indexes such as the Hirschman–Herfindahl index. It is affected by the number of the firms and asymmetry among the sizes of the firms; the smaller the number of firms and the more asymmetry among firms, the higher the market concentration index. The literature on mixed oligopolies suggested that the optimal degree of privatization increases with the number of private firms, and thus, decreases with the market competition index, assuming that all private firms are homogeneous. We investigate how asymmetry among private firms affects the optimal degree of privatization. We propose the simplest and natural model formulation to discuss asymmetry among private firms. We find that the optimal degree of privatization is either nonmonotone or monotonically increasing, and thus never monotonically decreasing, in asymmetry among private firms.     

董事会内在特征与上市企业绩效 ——基于董事会资本与董事会独立性状态视角

以上市企业为样本，分析异质性股权混合对董事会资本的影响，以及董事会资本与企业社会经济效益、企业经营效益和企业经营效率的关系，将资源依赖理论与代理理论相结合，检验董事会独立性与董事会资本对企业绩效的交互效应。研究结果显示，异质性股权混合有助于提高董事会资本水平，董事会资本有助于企业经营效益和社会经济效益的提升，董事会独立性和董事会资本二者同时作为治理机制治理效果会互补加强，二者单独对企业经营效率无影响，而是通过交互效应间接改善企业经营效率。
