VRP revisited: The impact of behavioural costs in balancing standardisation and variety

The objective of this paper is to bring a new element to the academic (and industrial) debate concerning the optimum level of variety in component design in mass production companies. Many authors have explored the trade-off between functional and variety costs, and this could be considered as a well-acknowledged management issue, at least from an engineering perspective. Nevertheless, while defining the theoretically optimal level of component variety, there are other elements, more related to operators’ attitude or to operative conditions, which may intervene and prevent effective exploitation of the existing variety. These elements have been given scant attention in literature, while they may play a relevant role in real organisations.In this paper, we will present a case study and an analytic model for these “behavioural costs” in manufacturing environments, so as to show how the theoretically optimal amount of variety changes if one takes into account these aspects. Researchers (and practitioners) might leverage on this contribution in order to rejuvenate the Variety Reduction paradigm, and to increase their awareness in designing and managing mass production manufacturing processes.     

Externalities,Cross-Sectoral Spillovers and Productivity Growth

We provide an interpretation of the productivity dynamics in the manufacturing sector based on the idea of the thick market externality à la Diamond. An econometric model has been estimated which allows to disentangle the long run effects of these trading externalities from those of internal economies of scale and of aggregate industry-level economies. The results obtained—based on a cointegrated system of non-linear-error-correction equations—confirm the hypothesis that the trading externality matters. Moreover, our findings point out that the emphasis generally posited both on internal and external economies of scale is not justified.     

Nutrition and growth in Italy, 1861-1911: What macroeconomic data hide

We investigate how nutritional status responded to economic growth in Italy during 1861-1911. By combining household-level data on food consumption with population censuses, we estimate that the incidence of undernutrition decreased by at least 15% between 1881 and 1901. Income elasticity of calories in 1901 was in the range of 0.3-0.6, varying inversely with the level income. Overall, our findings do not support the pessimists’ view, ubiquitous in the Italian literature. On the contrary, the early phase of Italian industrialization was beneficial to the bulk of the population, and even more so for the poorest among the poor.     

Revisiting the European Monetary System Experience: Were Some Members More Equal than Others?

Difficulties in implementing effective liquidity support – to counter speculative attacks – may partly explain why regional exchange rate agreements crawl regional trade integration. Our novel analysis of the European Monetary System confirms that liquidity support was provided under the discretion of the anchor country (Germany), and was indeed asymmetric across member countries and/or periods. In particular, it was less forthcoming (i) to countries further away from Germany (less politically influential there), (ii) to larger countries (interfering more with the Bundesbank's monetary control) and (iii) during periods when German inflation accelerated (and the Bundesbank needed a firmer grip on liquidity).     

Monetary Union, institutions and financial market integration: Italy, 1862–1905

Years into the single currency, EMU financial markets are not fully integrated. We argue that the phenomenon can be better understood by looking at financial markets’ behavior in the wake of Italy’s monetary unification (1862). Variables such as the spread of the telegraph, trade volumes, and the diffusion of the ‘single currency’ fail to explain why it took 25 years for prices across regional stock exchanges to converge. A single Italian financial market appeared only when the State prevailed upon local vested interests by enforcing nation-wide financial market legislation.     

A survey of cross-sectional and time-series literature on factors affecting child welfare

This paper reviews the literature on the socio-economic determinants of child welfare. Cross-sectional evidence is first analysed. The relevant literature is subdivided into four groups of studies depending on the main factors influencing child welfare: demographic; related to family circumstances; related to health care and sanitation; and economic. The very few time-series studies on this subject are then examined. While the existing literature does not allow definitive conclusions to be drawn on the predominance or relative importance of these four sets of factors, this paper identifies three related research areas for which particularly severe gaps seem to emerge and for which additional investigation appears necessary. These are: over-time studies, studies for low-income, high-mortality countries of Africa, for middle-income countries and for high-income, high-mortality countries, and studies measuring impact on the basis of indicators of welfare other than infant mortality rates.     

Is enterprise risk management real?

Moving from the growing relevance of the enterprise risk management (ERM) concept, this paper provides empirical evidence of ERM in practice. The paper presents ERM actual uses in a panel of nine Italian companies from different industrial fields and legislative settings and analyses the relationship between the uses and the characteristics of the ERM tool implemented in each case. The data analysis highlights the existence of different activities that are supported by the ERM tool and also different types of use (i.e. responsive, discoursive and prospective) corresponding to a different contribution of ERM to managerial action. These uses related to the specific characteristics of the tools generally indicated with the label ‘ERM’.     

Welfare Implications of a Preferential Tariff Reduction for Agricultural Exports from Less Developed Countries vs. a Generalized Tariff Reduction

The paper presents the results of a theoretical study focusing on a comparative evaluation of the welfare effects of a preferential tariff reduction for agricultural exports from less developed countries versus a generalized tariff reduction. The results are derived using a diagrammatic approach. The analysis is developed within a partial equilibrium framework with one commodity, three large countries (importing developed country, exporting developed country, developing country), fixed exchange rates and zero transportation costs. The theoretical model makes provisions for a country to switch from being an exporter to being an importer, or vice versa, as the equilibrium price changes. Three alternative policy scenarios are analyzed: the imposition of a non-discriminatory tariff, a preferential tariff reduction, and a generalized tariff reduction. Two alternative definitions of the welfare functions are used. One is based on consumers' and producers' surplus, the other adds domestic income and changes in foreign exchange earnings/expenditure. Some methodological implications of the specific model used are discussed, along with the impact, in terms of welfare, of the policy scenarios considered.     

An integrated multi-model credit rating system for private firms

This paper presents a integrated credit risk modelling approach for private firms which fulfil 2001 Basel Accord requirements in the case of the adoption of the foundation approach. Our model comprises: (a) a bottom-up technique to initially assess the through-the-cycle one-year Probability of Default (PD) and (b) a top-down approach to refine and calibrate this historical PD in a forward-looking credit risk assessment based on next year’s economic outlook. We present findings from applying this model to a large sample of client firms of the Bank of Rome.
