Sticky cost behaviour: evidence from small and medium sized companies

This paper investigates whether cost stickiness occurs in small and medium sized companies using a sample of Italian nonlisted and listed firms during the period 1999–2008. Our findings show that cost stickiness emerges only for the total cost of labour and not for selling, general and administrative (SG&A) costs, cost of goods sold and operating costs. Stickiness of operating costs is only detected in a sample of listed companies. We further contribute to the literature on sticky cost behaviour by discussing critical issues associated with the extant approach of empirical analysis and interpretation of sticky cost behaviour.     

Regulation and efficiency in transition: The case of telecommunications in Italy

In regulating the telecommunications industry, the separation between network and retail functions, which is designed to countervail the market power of incumbent operators, is a relevant issue. Despite its importance, little empirical research has addressed the effects of such a separation. Accordingly, this paper provides insights into the consequences of the Italian communications regulatory authority's (AgCom) decision to impose this type of separation on the incumbent telecommunications operator, Telecom Italia. In particular, the studied separation is between the firm's network-related functions, and those used for provision of its communication services. The present research finds that the type of separation implemented by AgCom allows a provider to maintain the advantages of operational scale in its network structure without dampening competition in the existing market for communications services. The study also offers further empirical evidence on the advantages of a composite vs. translog function in analyzing the multiproduct cost structure of a telecommunications operator.     

Trust,risk and time preferences: evidence from survey data

The paper shows that time preferences and risk preferences are key covariates of self-reported trust. They both predict negatively a measure of generalized trust; however, risk aversion is positively correlated with an index of particularized trusting behaviour (which refers to the circle of known people).     

A tale of two Italies: ‘access-orders’ and the Italian regional divide

ABSTRACT

This paper uses the ‘access orders’ paradigm developed by North, Wallis, and Weingast [(2009). Violence and social order: A conceptual framework for interpreting recorded human history. Cambridge: Cambridge University Press] to analyse the case of the Italian North–South economic divide. In line with their framework, we collect and discuss several social and political indicators over the long-run, at the regional level. Firstly we looked at data on the pre-conditions for the establishment of an open-access order, such as murders per capita (a proxy for control over violence), voting turnout and referendums participation (proxies for political legitimacy), and the impersonality of exchange. We then showed evidence of different access orders in the North and in the South, using the information on human capital formation, women participation in the labour market, and referendum results. On the basis of this evidence, we argue that, despite being part of the same State and subject to the same formal institutions, the North of the country progressively developed into an open-access order, while the South remained a form of limited access order.

Institutional differences are linked to specific aspects of the economic performance of the two areas, thus the ‘access order’ paradigm appears to be an effective conceptual scheme to explain the North–South economic divide.

Stratified realization of comparative probabilities

A definition of realization for comparative probabilities using coherent conditional probabilities is proposed in a finite setting and named stratified realization. The extent of stratified realization is examined in detail and comparisons are made with realization by means of a strictly positive, not necessarily bounded real measure (orP ₁-realization). Given a comparative probability which admits stratified realization, necessary conditions forP ₁-realization are found. A sufficient condition for the same problem is then proved, and the relationship with other forms of realization, is briefly discussed.

Sommario In questa nota viene proposta, in ambiente finito, una definizione di realizzabilità di prbabilità qualitative mediante, probabilità condizionate coerenti, detta realizzabilità stratificata. Tale nozione è basata su un'opportuna caratterizzazione delle probabilità condizionate coerenti e generalizza la realizzabilità con misure reali strettamente positive (oP ₁-realizzabilità).La realizzabilità stratificata viene esaminata in dettaglio, fornendo condizioni necessarie affinché una probabilità qualitativa realizzabile in tal senso sia ancheP ₁-realizzabile. Si prova poi per lo stesso problema una condizione sufficiente. Infine viene brevemente discussa la relazione fra realizzabilità stratificata e alcune altre nozioni di realizzabilità.

     

On inferior inputs and marginal returns

An input is inferior if and only if an increase in its price raises all marginal productivities. A sufficient condition for input inferiority under quasi-concavity of the production function is then that there are increasing marginal returns with respect to the other input and a non-positive marginal productivity cross derivative. Thus, contrary to widespread opinion, input “competitiveness” is not needed. We discuss these facts and illustrate them by introducing a class of simple production function functional forms. Our results suggest that the existence of inferior inputs is naturally associated with increasing returns, and possibly strengthen the case for inferiority considerably.     

Forecasting Long-Term Interest Rates with a General-Equilibrium Model of the Euro Area: What Role for Liquidity Services of Bonds?

This paper studies the forecasting performance of a general equilibrium model of bond yields where government bonds provide liquidity services and are, as such, an integral part of the monetary transmission mechanism. The model is estimated with Bayesian methods on Euro area data. I compare the out-of-sample predictive performance of the model against a variety of competing specifications, including that of De Graeve et al. (J Monet Econ 56(4):545–559, 2009). Forecast accuracy is evaluated through both univariate and multivariate measures. I also control the statistical significance of the forecast differences using the tests of Diebold and Mariano (J Bus Econ Stat 13(3):253–263, 1995), Hansen (J Bus Econ Stat 23:365–380, 2005) and White (Econometrica 68(5):1097–1126, 1980). The results indicate that accounting for the liquidity services of bonds contributes to generate superior out-of-sample forecasts for both real variables, such as output, and inflation, and for bond yields.     

Relational effects of relative performance information: The role of professional identity

Prior accounting studies on relative performance information (RPI) have mainly considered the effects of RPI on employees’ performance. This study extends this stream of research by investigating relational effects of RPI that capture RPI recipients’ attitudes towards RPI provision. Specifically, we examine the conditions under which RPI has a positive influence on perceived organizational support (POS). This is important because research on organizational behaviour has demonstrated that POS is an antecedent of desirable job-related attitudes such as organizational commitment, job involvement, and extra-role performance. The results of a dyadic survey in a hospital setting suggest that the effect of RPI on POS is conditional not only on the perceived usefulness of information and relative performance but also on the professional identification of RPI recipients. Our findings indicate that RPI provision is especially suitable for employees who possess a stronger social identification with their peer groups. Our study adds a relational perspective to the hitherto mostly informational and motivational focus in studying social comparison mechanisms linked to RPI systems.
