Compensations as signaling devices in the political economy of reforms*

We propose an explanation for why efficient reforms are not carried out when losers can block their implementation and compensations are feasible. In our model, a government tries to sequentially implement two efficient reforms by bargaining with interest groups. The organization of interest groups is endogenous. Compensations are distortionary and different governments care differently about distortions. Governments use low compensations to discourage losers who just want to receive transfers from organizing. This comes at the cost of reforms being blocked by interest groups with relatively high losses, resulting in a bias against payment of compensations and the implementation of reforms.     

The globalisation of technology and its implications for developing countries: Windows of opportunity or further burden?

On the basis of a categorisation of ways in which the generated knowledge is transmitted, this paper explores the impact of the different forms of the globalisation of technology on developing countries. Through travelling, media, scientific and technical workshops, Internet and many other communication channels, globalisation allows the transmission of knowledge at a much greater pace than in the past. However, this does not automatically imply that developing countries succeed to benefit from technological advances. On the contrary, this will strongly rely on the nature of the technology and of the policies implemented in both advanced and developing countries.     

Long-run Effective Demand in the US Economy: An Empirical Test of the Sraffian Supermultiplier Model

The Sraffian supermultiplier is a model of demand-led growth that stresses the importance of the autonomous components of aggregate demand (exports, public spending and autonomous consumption). This article tests empirically some major implications of the model employing macroeconomic data for the United States. In particular, we study the long-run relation between autonomous demand and output through cointegration analysis. The results suggest that autonomous demand and output are cointegrated and that autonomous demand exerts a long-run effect on output. There is also some evidence of simultaneous causality, especially in the short-run. Movements in autonomous demand and in the investment share are also found to be positively related, with Granger-causality going from Z to I/Y.     

Riding out of a financial crisis: The joint effect of trust and corporate ownership

We study how generalized trust shapes the ability of firms with different ownership forms to obtain trade financing and perform during a financial crisis. Exploiting geographic variations in trust across Italian regions and the occurrence of the 2008-09 financial crisis in a difference-in-differences setting, we show that generalized trust makes family firms less able to obtain trade financing during the crisis. This finding maps into performance results: trust alleviates the negative effect of a crisis for non-family firms, while it aggravates the negative effect for family firms. This latter result depends crucially on a firm's corporate governance: trust does not harm family firms whose board is open to non-family directors. Collectively, our findings illustrate how culture interacts with corporate attributes in shaping a firm's prospects.     

The Impact of Degree Duration on Higher Education Participation: Evidence from a Large‐scale Natural Experiment

This paper investigates the effects on enrolment, retention rate and on‐time graduation of a nationwide Bologna Process reform introduced in Italy to establish BAs with a duration of three years, followed by optional second‐tier degrees of two years, in place of single‐tier degrees of four or five years. The analysis exploits exogenous delay of treatment conditions and the unique availability of microdata that cover the universe of the departments. We estimate that the reform boosted first‐year enrolments by 14.5–17.3 percentage points, compared to a counterfactual status of no reform. This enrolment shift was due to participation gains rather than substitution effects, and it is likely to have persisted in the longer term. Moreover, no trade‐off between increased participation and deteriorated retention and on‐time graduation emerged.     

On the role of unobserved preference heterogeneity in discrete choice models of labour supply

The aim of this paper is to analyse the impact of unobserved preference heterogeneity in empirical applications of discrete choice models of labour supply. Typically, unobserved heterogeneity is estimated either with continuous or discrete mixture models. However, in order to avoid estimation difficulties, most of the empirical analysis assumes a relatively constrained mixture, standard examples being models where only few coefficients are allowed to vary with independent normal distributions or with discrete distributions with few mass points. We compare labour supply elasticities obtained with these typical specifications of unobserved heterogeneity with those from a more general model that we are able to estimate through an EM algorithm for the nonparametric estimation of mixed models. Results show that labour supply elasticities change significantly with respect to a basic model without unobserved heterogeneity only when the joint distribution of the varying tastes is left completely unspecified.     

Estimating Market Power by Retailers in a Dynamic Framework: the Italian PDO Cheese Market

In this article, we evaluate the role of market power by retailers within the supply chain of Parmigiano Reggiano (PR) and Grana Padano (GP), the two most famous Italian quality cheeses. Market power is analysed in the context of a dynamic imperfect competition model of the supply chain, in which retailers are allowed to exert market power both downstream and upstream. We jointly estimate market‐power parameters together with supply and demand elasticities, by means of a structural system of demand, supply and price‐transmission equations, estimated using the generalised method of moments. We find evidence of downstream market power by retailers (toward final consumers) for PR and GP, but no evidence of upstream market power (toward processors/ripeners). These results may be explained by the structure of the supply chain and by the peculiar characteristics of the two cheeses.     

Evolutionary variational inequalities and applications to complex dynamic multi-level models

In this paper we consider a supply chain network model with three tiers of decision-makers (manufacturers, retailers, and consumers) in the case when prices and shipments are evolving on time. Moreover, we assume that excesses of production and excesses of demand of the commodity are present. For such a framework we furnish, using the infinite dimensional duality theory, the equilibrium conditions for the representatives of each tier of the supernetwork, the time-dependent variational formulation governing the complete supply chain supernetwork, and we provide some existence theorems and a numerical example.     

The spinning jenny and the guillotine: technology diffusion at the time of revolutions

Scale economies and demand, combined with the relative prices of input factors, can provide an economic explanation to the location and timing of the Industrial Revolution. Its labor-saving innovations were profitable only above a minimum output threshold, which allowed to cover the upfront cost of capital. In turn, the possibility to exceed such threshold depended on consumer demand, which was affected by the level and by the distribution of real income. The case of the spinning jenny and the cotton industry in England and France serves as a valuable case study to show how scale and demand considerations might have mattered even at the eve of the Industrial Revolution, thus implying also a potentially important role for income distribution.     

Asymmetric Perception of Sparse Shelves in Retail Displays

We investigated a perceptual bias in recognizing partially stocked shelves in retail displays. Across a series of experiments, a total of 475 right-handed participants were asked to discriminate between pairs of store displays that were more versus less stocked with items. When asked to identify the sparser display in a sterile environment, participants were significantly faster and more accurate in responding to images presented in the left visual field (LVF) than to images presented in the right visual field (RVF). The perceptual asymmetry persisted in a realistic setting, and was prominent under conditions of high task difficulty. The results are consistent with a view of this sparse-shelf bias as emerging from selective hemispheric activation to quantities rapidly assessed during a shopping trip.
