Externalised vs. internalised consumption of luxury goods: propositions and implications for luxury retail marketing

This study conceptualises the dichotomy of luxury goods consumption (‘externalised luxury’ vs. ‘internalised luxury’) in terms of six dimensions: on the one hand ostentation, materialism and superfluousness (which refer to luxury as a social statement) and, on the other hand individual lifestyle, emotions/hedonism and culture (which refer to luxury as individual style). Through this literary framework, it presents a series of propositions that might be tested in future research, one for each dimension, about retail strategies and operations for fashion luxury brands. Implications for retail managers of luxury companies are discussed for each proposition, considering the main aspects of retailing strategies and tools (e.g. assortment, sales force, in-store experience and atmospherics) together with possible theoretical developments.     

Longevity and life expectancy

The increase in life expectancy at all ages during the last two centuries is in need of a quantitative model capable of resuming the whole process under a single concept and simple mathematics. The basic hypothesis was that through improved hygiene, medicine, and life-style, the stumbling blocks to the full expression of longevity were progressively removed. The mathematics of learning processes was then applied to the secular evolution of life expectancy at various ages. The hypothesis proved very fertile. Logistic equations fit long strings of statistical data, covering the evolution of life expectancy at various ages, for both sexes, and in many European nations for almost two centuries. These life expectancy increases seem to move progressively to a common asymptote of about 79 years for men and about 84 years for women. It is suggested that these values are taken as a definition of longevity, presumably explicitating a coding in DNA. The evolution of life expectancy during the last couple of centuries appears to follow consistent paths precisely mapped with simple mathematics. This opens the way to more integrated and holistic theories.

Affiliates and parent employment through foreign direct investment: a study case of substitutability or complementarity

How does outward foreign direct investment (FDI) affect employment of multinationals in the home country? Does the impact of outward investment differ among manufacturing and service sectors? Using data on Italian MNEs, this paper examines the impact of Italian outward FDI on local employment between 1998 and 2006. In particular, we investigate the relationship existing between employment in the parent company and employment in foreign affiliates by distinguishing according to host-country location and sector of activity. The results suggest that the effects of Italian outward FDI on domestic employment differ according to the sector and the country of destination. In the manufacturing sector, a weak but significant relationship of labour substitutability is found for Italian MNEs producing low-technology products in foreign affiliates localized in high-wage countries. On the other hand, a significant North–south complementarity relationship in labour demands appears in the High and Medium-high- technology sectors. In the service sector, we find strong complementarity between employment in the parent firm and employment in foreign affiliates: in particular, this regards Italian MNEs producing knowledge-intensive services both in Western affiliates and CEEC locations. These results are robust when we control for endogeneity of output and parent wages.     

Pollution Accumulation and Firm Incentives to Accelerate Technological Change Under Uncertain Private Benefits

The paper explores the relationships between the design of public incentives and the policy-maker's desired timing of abandonment of a polluting technology, when this requires an irreversible private investment and the firm faces uncertain appropriable benefits from the technological change. Two regulatory approaches are examined. Firstly, we consider the quite common one of lowering the private investment cost, through a subsidy, in order to bridge the gap between the private and the policy-maker's desired timing of environmental innovation. Secondly, we consider a policy scenario where the regulator, instead of simply lowering the investment's rental price, also stimulates abandonment of the polluting technology by reducing – through appropriate announcements – the uncertainty surrounding the technological switch's private profitability. We then compare the two approaches and show the latter's benefits, in terms of the policy's effectiveness and/or budgetary savings.     

The Reform of Local Public Utilities in Italy

The Italian system of local public utilities has recently undergone an important reform process. The first round of reforms, introduced in the 1990s, represented a remarkable change in the social welfare function with regard to the management of local public utilities. The legislation was specifically designed to cut costs and reduce deficits. A second round of reforms, required by European directives, started around the mid-1990s. Several laws were passed introducing important innovations and regulating specific sectors: public transport; electricity; and gas. Article 35 of the 2002 Financial Law was the final step in a comprehensive reform of the whole local public utility sector. The main innovations of the Financial Law concerns liberalization. Article 35 states that the general rule for awarding service provision contracts is competitive tendering; the rationale is obviously that of competition for the market. The general rule as expressed by Article 35 is nevertheless limited during the transition period. In the long run, competitive tendering will become the normal way of awarding contracts for local public utility provision. Even if there are doubts that full competition will be introduced into the sector, liberalization does appear to be having an effect, forcing many local public utilities to become more efficient. The changes introduced have brought about a better and a more efficient system with a greater number of large size enterprises and on the average a more active management.
In the future, the liberalization process may come to a standstill due to an insufficient number of competitors. Strong public administrations are therefore needed to prevent opportunistic behaviour by private firms.     

Chi-squared tests for evaluation and comparison of asset pricing models

This paper presents a general statistical framework for estimation, testing and comparison of asset pricing models using the unconstrained distance measure of Hansen and Jagannathan (1997). The limiting results cover both linear and nonlinear models that could be correctly specified or misspecified. We propose modified versions of the existing model selection tests and new pivotal specification and model comparison tests with improved finite-sample properties. In addition, we provide formal tests of multiple model comparison. The excellent size and power properties of the proposed tests are demonstrated using simulated data from linear and nonlinear asset pricing models.     

Asset pricing models and economic risk premia: A decomposition

The risk premia of linear factor models on economic (non-traded) risk factors can be decomposed into: i) the premium on maximum-correlation portfolios mimicking the factors; ii) (minus) the covariance between the non-traded components of the pricing kernel and the factors; and iii) (minus) the mispricing of the maximum-correlation portfolios. For a given set of assets available for investment, the first component is the same across models and is typically estimated with little bias and high precision. We conclude that the premia on maximum-correlation portfolios are appealing alternatives to the risk premia of linear factor models, with the dividend yield being the only economic factor significantly priced.
