Test power properties of within-firm estimators of ownership and board-related explanatory variables with low time variation

Review of Quantitative Finance and Accounting - After decades of fast growth, the Chinese housing market has become twice as large as the US housing market. In this paper, we examine the effect of...     

Empirical analysis of the relationship between labour cost stickiness and labour reforms in Spain

This study performs an empirical analysis on the relationship between labour cost stickiness and the decrease in employment protection in the Spanish labour reforms in 2010 and 2012. Following these reforms, the sticky behaviour of labour costs substantially decreased with respect to the pre-reform period. All constituents of total labour costs followed a similar pattern: wages, social security contributions and number of employees. Results are robust to different models, estimation methods, periods of time, and industries, as well as with respect to endogeneity concerns.     

The Effects of Immigration on Labour Tax Avoidance: An Empirical Spatial Analysis

We investigate whether the geographic concentration of non-EU immigrants in the various Italian provinces affects labour tax avoidance (LTAV) practices adopted by firms located in the same provinces, as well as in the neighbouring provinces, and operating in construction and agriculture industries that mostly employ immigrants in Italy. For this purpose, we develop a LTAV proxy based on the financial accounting information of a sample of 993,606 firm-years, disseminated throughout the 108 Italian provinces, over the period 2008–2016. Our results, based on a Spatial Durbin Model panel regression, reveal a statistically significant positive association between the concentration of non-EU immigrants and LTAV at province level, as well as the presence of spillover effects among neighbouring provinces. Our findings are robust to several additional analyses, including instrumental variable estimations. Our study provides empirical support to previous structuralist or marginalization theories holding that socioeconomically marginalized groups, such as non-EU immigrants, are more likely to be involved in labour exploitation practices, which could underlie our LTAV outcomes. Furthermore, it supports the need for tax authorities to strengthen labour inspections, coordinated at national level, especially in those contexts where non-EU immigrants are mostly employed. On the other hand, a greater social integration, assistance, and recognition of rights of immigrants may help to alleviate their situation of weakness that makes them more vulnerable to LTAV practices. Finally, tackling LTAV, associated with the underemployment of immigrants, may prevent its negative effects for society arising from the reduction of public resources to sustain the social welfare and finance public goods and services.

     

Misallocation and aggregate productivity across time and space

Productivity is at the core of the large differences in income per capita across countries. What accounts for international productivity differences? I discuss cross‐country differences in the allocation of inputs across heterogeneous production units—misallocation—as a potential factor in accounting for aggregate productivity. Policies and institutions generating misallocation are prevalent in poor and developing countries and may also be responsible for differences in the selection of operating producers and technology used, contributing substantially to aggregate productivity differences across countries.     

Inflation Differentials in a Currency Area: Facts,Explanations and Policy

The determinants of inflation differentials in a currency area are analyzed both from an empirical and a theoretical perspective. The empirical analysis shows that a sizeable dispersion of HICP inflation rates across euro-area countries arises mostly in the components based on non-traded goods. There is also a significant cross-country heterogeneity in the response to changes in a common latent factor which accounts for a large fraction of the dispersion in national inflation rates. A stylized model of a currency area is used to understand the interrelation among shocks, structures and policies in driving the data generating process. The model shows that the dynamic of the inflation differentials is largely driven by the variability of productivity in the non-tradable sector of the more flexible economy. Conversely, the output differentials is largely driven by the variability in the productivity of the tradable sector, also of the more flexible economy. Optimal policy is investigated together with an analysis of the optimal adjustment to adopting a common currency with initial incorrect real exchange rate parity.     

Cooperation versus competition in product innovation

This paper analyzes the optimal antitrust policy in the context of a patent race. In a simplified model, we identify the conditions under which allowing cooperation yields greater welfare than imposing competition. In view of our results, we discuss, critically, the current European policy towards R&D cooperation.     

Relatedness of decisions in business services outsourcing

The literature of service outsourcing is mainly focused on case studies or specific service activities. However, there is no evidence about the pattern of relatedness among outsourcing of services. This paper analyses this issue by a relatedness index previously applied in the framework of product and technological diversification. The index is applied to analyse the degree of relatedness for outsourcing decisions among an array of fourteen services in a large data set of Spanish manufacturers in 1990–2006, detecting four time-constant clusters. An econometric analysis tests the alternative explanations about this pattern of joint decisions, based on shared knowledge and on workers' expertise.     

The dynamics of exports and R&D in SMEs

A growing body of literature is exploring firm export and R&D activities. However, most studies examine the first one, whilst considering the second as an explanatory variable or vice versa. This paper contributes to this literature by exploring the joint dynamics of exports and R&D using data from a representative sample of small and medium-sized enterprises in Spanish manufacturing over the 1990–2006 period. The results confirm the existence of a strong interdependence between export and R&D activities. Indeed, engaging in export (R&D) activities will increase a firm’s chances of also engaging in R&D (export) activities. This, in turn, increases firms’ chances of succeeding in export (R&D) activities. Additionally, once we control for firm heterogeneity, strong persistence still remains in each activity due to true state dependence. The results are robust in the use of alternative measures of internationalization (i.e. imports) and innovative activities (product and process innovation).     

Optimierte Integration der Elektromobilität in das Stromversorgungssystem bei hohen Anteilen erneuerbarer Energien

Electric mobility will play a key role for the transformation of the energy supply in Germany [the “Energiewende”]. A successful market development of plug-in hybrids and battery electric vehicles and a full fleet penetration in the long-term are the most efficient and effective measure for integrating large amounts of renewable energy into the transport sector and for reaching the efficiency targets. These new electricity consumers in the supply system will cause additional electricity loads strongly dependent on the mobility needs of the vehicle users. A controlled battery charging is able to avoid new peak demands and to increase the efficiency of the power generation system by using excess power. By scenario analysis, the German Aerospace Center (DLR) in cooperation with the Fraunhofer Institute for Solar Energy Systems (ISE) and the Institute for High Voltage Technology of the RWTH Aachen investigated a possible successful development path of electric mobility in Germany and its integration into and interaction with the future power supply system. From both perspectives—the one of the total supply system as well as the other of local distribution grids—the results show promising potentials but also limits.
