Public support for performing arts. Efficiency and productivity gains in eleven European countries

This paper investigates the importance of public cultural expenditure for the efficiency and productivity of the performing arts (PA) firms. To this aim, we estimate a translog production function using the stochastic frontier approach (SFA), and we obtain the estimates of both technical efficiency and its determinants for the PA firms in EU-11 countries over the period 2009–2017. The large panel data set enables the application of robust true random-effects SFA techniques, which control for noise, unobserved firms' heterogeneity and endogeneity of the inputs. Moreover, by estimating a production function, the characteristics of the production technology in the PA sector is also derived. The empirical results demonstrate that PA firms are technically inefficient, implying that the investigated firms could increase their artistic output between 32 and 42% and that decreasing returns to scale are prevalent, due to the presence of too many micro and large-scale firms in the European PA sector. In contrast to the seminal Baumol and Bowen's [5] paper, we also demonstrate that the total factor productivity (TFP) increased in the EU PA firms over the examined period. Technical efficiency, although relatively low, was the main driver of this productivity growth, as opposed to scale efficiency change or technological change, which display very small or no increases. We also find that, contrary to the common wisdom on its negative effects on firm efficiency, public spending on culture increases the efficiency of PA firms. Within this context some policy implications are discussed.     

Overall corporate strategies for new product programs

The strategy an industrial firm elects for its product development program is increasingly viewed as a critical element of the firm's total corporate strategy. New product development and technology bear an integral relationship to an industrial company's strategic direction by helping to define the range of its possibilities [13]. This article reports the results of an empirical study whose purpose was to identify the major types of innovation strategies that firms pursue—strategy scenarios. A second purpose was to assess which strategies yield the best results.

Was household internet adoption driven by the reform? Evaluation of the 2013 telecommunication reform in Mexico

In 2013 the Mexican Telecommunications and Broadcasting Reform was launched with the goal of promoting competition and access in the telecommunications sector. The aim of this paper is to evaluate whether the 2013 reform had an impact on household fixed internet adoption and to what extent Mexican households, classified into ten wealth groups, had adopted internet. For the assessment, after a revision of supply and demand Reform's measures to reduce the digital divide, data from the 2010 Census and 2015 Intercensal Survey were used to create adoption indexes using Poisson estimations. The results were analyzed by ten wealth groups, constructed on principal components based on household characteristics (type of dwelling, electricity availability, availability of drinking water, sewer system, internet and ICT devices: computer, telephone, cell phone and internet). Additionally, the impact of both indexes was validated by a difference in differences method. The results suggest a 66% overall increase in internet adoption between 2010 and 2015. The decile analysis showed considerable internet adoption in the low and middle wealth groups (deciles 2–8), while in the highest wealth groups (deciles 9–10) the impact of internet adoption has been relatively moderate. It is worth noting that internet adoption is unequally distributed, as less than 1% of households in deciles 1 to 6 had adopted internet in 2015, while nearly all of the wealthiest ten percent of households have internet access. Nevertheless the increment in internet adoption was not only the result of the reform but the combination of the broadband penetration trend and the reform together.     

The EU State aid policy for broadband: An evaluation of the Italian experience with first generation networks

State aid (SA) measures for broadband have been flourishing in the EU, but our knowledge about the effectiveness and efficiency of this policy remains extremely scarce. We investigate the SA experience with the first generation of broadband services (FGB) in Italy, whose market was long plagued by extensive market failures, largely due to market power. By exploiting original open Government data and sources, we analyse the main domains of the EU SA policy, and assess whether its ex ante goals have been met in Italy. Four main results stand out. First, the plan extended the FGB coverage of rural areas, although with a substantial delay and incompletely, with respect to the ambitious targets of the Digital Agenda for Europe. Second, public consultations have significantly increased the transparency of the market and of the SA intervention, promoting investment and a gradual increase in the efficiency of public procurement. Third, the direct effects of SA on competitive entry appear less pronounced, at least in the static sense. Fourth, the final matching between allocative and dynamic efficiency of SA policy, and its coherence with industrial and innovation policies remain critical, based on the Italian experience: in fact, the persisting digital divide affecting the business-rich areas depicts another relevant instance of partial Government failure.     

Shared ownership and pricing in a network switch

We observe that many wholesale switches in automated teller machine (ATM) networks are jointly owned by their members and that this tends to occur more frequently when the wholesale industry is highly concentrated. We also observe that network switches are ‘natural monopolies’, their costs being largely fixed and their demand exhibiting substantial network externalities. Motivated by these observations, we model the competition for members between wholesale switches and the role joint ownership can play in attracting members. The model analyzes both the adoption decision (which network a bank chooses to join) and the subsequent pricing of switch and ATM services. We compare competition between two solely owned switches with competition between one solely owned and one jointly owned switch. Our analysis shows that a more concentrated structure results under the latter and that retail prices are higher. This calls into question the leniency of antitrust policy toward jointly owned structures.     

Enterprise modeling and integration: A stochastic management approach

Recently, my book by Matsui has been published in Japanese, and the title is “Management of Manufacturing Enterprise: Profit Maximization and Factory Science.” Enterprise/Factory Science means the system science of the 3M & I, in which is the complex of huMan, Material/Machine, Money and Information, and would contribute to enterprise modeling and integration issues. This paper presents the problem of enterprise/factory science, and discusses a class of 3M & I system by a stochastic management approach. First, the 3M & I system is defined, and a variety vs. structure is introduced. Next, the two structures of management are distinguished, and the demand-to-supply and process-cycle management are discussed by structural modeling.     

WHY DO LARGE FIRMS TEND TO INTEGRATE VERTICALLY?

We provide a theoretical framework to discuss the relation between firm size and vertical structures. The framework is based on a Hotelling model with three downstream and three upstream firms. We show that vertical integration enhances the degree of product differentiation and show the strategic complementarity of product positioning. We also show that the downstream firm that has the largest market share is more likely to integrate vertically. Enhancing the degree of product differentiation is more beneficial for the large firm than for the rest of the downstream firms because the large firm supplies a large amount of product.     

The role of credit officers in the performance of micro loans

This paper proposes a structural model explicitly considering the role played by credit officers in loan performance. The credit officer's ability is decomposed into the screening and the audit stage. This model is estimated using a rich database from VivaCred – a Brazilian NGO. Results suggest that: (i) there is substantial heterogeneity among credit officers in the sample; (ii) their ability affects more the screening than the audit stage; and (iii) their estimated ability is correlated with their experience at VivaCred but not with their experience before joining the organization. Evidence suggests that a reduction in staff turnover would be beneficial to the institution.
