Bridging boundaries in consumption,markets, and culture

ABSTRACT

This article introduces a special issue of Consumption Markets & Culture on “Bridging Boundaries in Consumption, Markets and Culture” presenting research by scholars based around the globe. Together, their work examines ways in which the dynamic relations between consumer actions, the marketplace, and cultural meanings bridge boundaries in consumption, markets, and culture. All of the studies rigorously showcase new ways of addressing enduring problems, demonstrating the rich analyzes that emerge when researchers dare to bridge boundaries between multiple perspectives in theory building.     

Measuring (in a time of crisis) the impact of broadband connections on economic growth: an OECD panel analysis

Technological innovation has always been considered a major stimulus for economic growth. High-speed internet access via broadband infrastructure has undergone rapid development since the end of the 1990s, thanks to the deployment of both fixed and mobile technologies. The present study investigates the impact of fixed broadband diffusion as a technological determinant of economic growth on the basis of a panel of 23 OECD countries over 15 years (1996–2010). The time horizon chosen is suitable for verification of the causal effect on growth of the transition from traditional copper to partially fibre networks. Through implementation of a dynamic panel by using the generalized method of moments (GMM) combined with an instrumental variable (IV) two-stage approach, we found a positive correlation between broadband diffusion and economic growth, even after controlling for countries initial endowment of information and communication technologies (ICT) and for the years of economic crisis. Our main finding provides evidence, through a continuous time interpretation of our estimations, of a quantitatively relevant relationship between broadband diffusion and economic dynamics in the short, medium and long runs. Our findings may be useful to policy makers in that they permit forecasting of the benefits of further transition from broadband to ultra-wide broadband networks.     

Capital Budgeting in Multidivision Firms: Information, Agency, and Incentives

We examine optimal capital allocation and managerial compensationin a firm with two investment projects (divisions) each runby a risk-neutral manager who can provide (i) (unverifiable)information about project quality and (ii) (unverifiable) accessto value-enhancing, but privately costly resources. The optimalmanagerial compensation contract offers greater performancepay and a lower salary when managers report that their projectis higher quality. The firm generally underinvests in capitaland managers underutilize resources (relative to first-best).We also derive cross-sectional predictions about the sensitivityof investment in one division to the quality of investment opportunitiesin the other division, and the relative importance of division-leveland firm-level performance-based pay in managerial compensationcontracts.     

Privatization and stock market liquidity

This paper shows that share issue privatization (SIP) is a major source of domestic stock market liquidity in 19 developed economies. Particularly, privatization IPOs have a negative effect on the price impact – measured by the ratio of the absolute return on the market index to turnover. This result is robust to the inclusion of controls for other observable and unobservable factors, having also considered the endogenous nature of the decision to privatize.     

Does the internet defy the law of gravity?

We show that gravity holds in the case of digital goods consumed over the Internet that have no trading costs. Therefore trade costs cannot fully account for the effects of distance on trade. In particular, we show that Americans are more likely to visit websites from nearby countries, even controlling for language, income, immigrant stock, etc. Furthermore, we show that this effect only holds for taste-dependent digital products, such as music, games, and pornography. For these, a 1% increase in physical distance reduces website visits by 3.25%. For non-taste-dependent products, such as software, distance has no statistical effect.     

Aspects of University Research and Technology Transfer to Private Industry

University research in the U.S.A. is based on a tight relationship between University and economic activity. In Europe and South America, although less commonly than in the U.S.A., there's already a large amount of experiences related to the creation of "on campus" or "spin off" companies based on the results and knowledge obtained from research in University departments and R&D centres financed with public funds. The virtual base of this results in communication technologies enables private use and the appropriation of the benefits by their authors. European model, historically widely separated from private companies, has produced high quality basic research, but it has failed to obtain profit from technological development. Research funds happen to be basically public. Europe heads for economic, politic and military union. Common economic space and the growing up of the new markets, which we can foresee to be extended to other countries, will promote business opportunities and the relationship University-Industry. University institutions and faculties should think about their current ethic convictions to create a new Industry-University model in the context of a global economy.     

Bayesian Hypothesis Testing: a Reference Approach

For any probability model M={p(x|θ, ω), θεΘ, ωεΩ} assumed to describe the probabilistic behaviour of data xεX, it is argued that testing whether or not the available data are compatible with the hypothesis H₀={θ=θ₀} is best considered as a formal decision problem on whether to use (a₀), or not to use (a₀), the simpler probability model (or null model) M₀={p(x|θ₀, ω), ωεΩ}, where the loss difference L(a₀, θ, ω) –L(a₀, θ, ω) is proportional to the amount of information δ(θ₀, ω), which would be lost if the simplified model M₀ were used as a proxy for the assumed model M. For any prior distribution π(θ, ω), the appropriate normative solution is obtained by rejecting the null model M₀ whenever the corresponding posterior expectation ∫∫δ(θ₀, θ, ω)π(θ, ω|x)dθdω is sufficiently large. Specification of a subjective prior is always difficult, and often polemical, in scientific communication. Information theory may be used to specify a prior, the reference prior, which only depends on the assumed model M, and mathematically describes a situation where no prior information is available about the quantity of interest. The reference posterior expectation, d(θ₀, x) =∫δπ(δ|x)dδ, of the amount of information δ(θ₀, θ, ω) which could be lost if the null model were used, provides an attractive nonnegative test function, the intrinsic statistic, which is invariant under reparametrization. The intrinsic statistic d(θ₀, x) is measured in units of information, and it is easily calibrated (for any sample size and any dimensionality) in terms of some average log‐likelihood ratios. The corresponding Bayes decision rule, the Bayesian reference criterion (BRC), indicates that the null model M₀ should only be rejected if the posterior expected loss of information from using the simplified model M₀ is too large or, equivalently, if the associated expected average log‐likelihood ratio is large enough. The BRC criterion provides a general reference Bayesian solution to hypothesis testing which does not assume a probability mass concentrated on M₀ and, hence, it is immune to Lindley's paradox. The theory is illustrated within the context of multivariate normal data, where it is shown to avoid Rao's paradox on the inconsistency between univariate and multivariate frequentist hypothesis testing.     

Trade, technology, and the rise of the service sector: The effects on US wage inequality

This paper uses a multi-sector version of the Ricardo-Viner model of international trade to quantify empirically the effects of technological changes, international trade, changes in the sectoral composition of the economy, and other factors on the US wage premium. The main finding of the paper is that changes in the sectoral composition of the economy were the most important force behind the widening of the wage gap, accounting for about 60% of the relative increase in wages of skilled workers between 1970 and 1996. In essence, capital was reallocated to sectors where it is relatively complementary to skilled workers.     

Collective Bargaining and the Evolution of Wage Inequality in Italy

Italian male wage inequality has increased at a relatively fast pace from the mid‐1980s until the early 2000s, while it has been persistently flat since then. We analyse this trend, focusing on the period of most rapid growth in pay dispersion. By accounting for worker and firm fixed effects, it is shown that workers' heterogeneity has been a major determinant of increased wage inequalities, while variability in firm wage policies has declined over time. We also show that the growth in pay dispersion has entirely occurred between livelli di inquadramento, that is, job titles defined by national industry‐wide collective bargaining institutions, for which specific minimum wages apply. We conclude that the underlying market forces determining wage inequality have been largely channelled into the tight tracks set by the centralized system of industrial relations.     

A simple model of income,aggregate demand and the process of credit creation by private banks

This paper presents a small macroeconomic model describing the main mechanisms of the process of creation by the private banking system. The model is composed of a core unit—where the dynamics of income, credit and aggregate demand are determined—and a set of sectoral accounts that ensure its stock-flow consistency. In order to grasp the role of credit and banks on the functioning of the economic system we make an explicit distinction between planned and realized variables, thanks to which, while maintaining the ex-post accounting consistency, we are able to introduce an ex-ante wedge between current aggregate income and planned expenditure. Private banks are the only economic agents capable of filling this gap through the creation of new credit. Through the use of numerical simulation we discuss the link between credit creation and the expansion of economic activity, also contributing to a recent academic debate on the relation between income, debt and aggregate demand.
