SERVCON: development and validation of a multidimensional service convenience scale

As customers have demanded greater convenience in service exchanges, researchers have responded by incorporating the convenience construct into their conceptual models and empirical studies, but a comprehensive, formally validated measure of convenience remains lacking. This study conceptualizes service convenience as a second-order, five-dimensional construct that reflects consumers’ perceived time and effort in purchasing or using a service. Service convenience dimensions are salient at different stages of the purchase decision process. Given this conceptualization, the study presents the development and validation of the SERVCON scale, a comprehensive instrument for measuring service convenience. The five dimensions are independent within a nomological network that illustrates distinct antecedent and consequent effects, and the results reinforce the multidimensional representation, offering insight into the distinctive relationships between each service convenience dimension and its antecedents, such as competitive intensity, and consequences, such as repurchase behavior. The findings help researchers and managers understand a fully conceptualized convenience construct and facilitate the measurement of convenience in future empirical studies.     

Linking product modularity and innovativeness to supply chain management in the Italian furniture industry

Much of the literature on modularity assumes that firms with modular products adopt modular organization. In the realm of supply chain management, no consensus has been reached on the effects of product modularity on supply chains (SC). This paper investigates whether SC choices depend on product modularity and innovativeness, and how SC choices can be aligned to these product features to maximize performance. A medium scale survey has been performed in the Italian furniture industry. By means of factor and cluster analyses, the SC of firms that introduced products with different levels of modularity and innovativeness have been compared. The results show that both product features must be considered when designing the SC.     

Relational paths in business network dynamics: Evidence from the fashion industry

This paper addresses the topic of business network dynamics. Starting with a review of the IMP literature, it aims to shed light on potential relational paths by which a firm may reconfigure its business network. To this end, two main emerging paths are described: integration and substitution. Methodologically, the paper presents and discusses the data collected during a longitudinal case analysis of four Italian textile producers. The main implications for business networks stemming from these emerging relational paths are described. In particular, the main findings from the cases analyzed suggest that business network dynamics should be interpreted in terms of the processes of both business network change and consolidation.     

Embedded markets: A dialogue between F.A. Hayek and Karl Polanyi

The recent economic crisis has once more underscored the close connection between markets and social life, thrusting this point at the centre of the analysis of economic and political activity and has once more asked the question of whether and how individuals are embedded in both. Here I argue that an analysis and partial reconciliation of the positions of F.A. Hayek and Karl Polanyi on the topic can help in this debate.     

The impact of ECB and FED announcements on the Euro interest rates

We investigate the impact of news in the ECB and FED monetary policy announcements on daily changes in Euro interest rates. We document significant impacts of ECB announcements throughout the period but only until mid 2004 of FED announcements.     

Profit rate dynamics, income distribution, structural and technical change in Denmark, Finland and Italy

Under less restrictive assumptions than in previous contributions, this paper highlights various patterns of profit rate dynamics that are common to the countries under scrutiny. Without a substantial re-distribution of income in favour of profits, the profit rate declines. When labour productivity is weak the profits/wages ratio declines leading to a decline in the profit rate, also due to capital deepening. Developments in the capital-labour ratio tend to increase the organic composition of capital while those in the ratio between the capital price deflator and the average wage tend to decrease it. Falls in the profit rate took place in countries with a weak technological change with episodes of Marxian bias. Employment shifted from low to high capital intensity sectors, from low to high organic composition industries and from low to high productivity sectors. Rising strength of labour and realization failures tend to have a greater role than rising organic composition in cyclical profit rate dynamics. Over the cycle, the first mechanism is also the first one to show up, while the others tend to follow it. Theoretical and policy implications are offered.     

An empirical investigation into the gravitation and convergence of industry return rates in OECD countries

Tests are offered for the hypotheses that sectoral average profit rates and incremental return rates are gravitating around or converging towards a common value. We study data for various OECD countries relying on an econometric method able to account for residual autocorrelation and cross‐sector correlation. Our null hypotheses receive only a mixed empirical support. This is interpreted as the result of various kinds of limitations to capital mobility. Policy implications are discussed.     

The Italian financial cycle: 1861–2011

In this paper, we investigate the main features of the Italian financial cycle, extracted by means of a structural trend-cycle decomposition of the credit-to-GDP ratio, using annual observations from 1861 to 2011. In order to draw conclusions based on solid historical data, we provide a thorough reconstruction of the key balance sheet time series of Italian banks, considering all the main assets and liabilities over the last 150 years. We come to three main conclusions. First, while there was close correlation between loans and deposits (relative to GDP) until the mid-1970s, over the last 30 years, this link became more tenuous and the volume of loans has increased in relation to deposits. The banks covered this “funding gap” mainly by issuing new debt securities. Second, the Italian financial cycle has a much longer duration than traditional business cycles. Third, taking into account the deviation of the credit-to-GDP ratio from its trend, an acceleration of credit preceded or accompanied a banking crisis in 8 out of the 12 episodes listed by Reinhart and Rogoff (This time is different: eight centuries of financial folly. Princeton University Press, Princeton, 2009). A Logit regression confirms a positive association between the probability of a banking crisis and a previous acceleration of the credit-to-GDP gap. However, there were also periods—such as the early 1970s—in which the growth of the credit-to-GDP ratio was not followed by a banking crisis.     

Will East Germany Become a New Mezzogiorno?

Despite massive regional policy efforts, GDP per capita in Southern Italy has only briefly converged on Northern Italian levels in the 1960's. Failure of convergence since then is associated with a policy switch from investment toward income maintenance, with reduced wage sensitivity to regional labor market conditions and with increases in rent-seeking opportunities and corruption. East Germany's early experience of rapid wage and income, but not productivity, convergence raised fears that aMezzogiornoscenario could be repeated. Since then, however, investment and productivity have risen while wage setting has become more flexible. Given East Germany's greater “social capability” for growth, and provided that investment continues to be encouraged, the prospects for convergence are now more promising.J. Comp.
