Public utility planning and cost efficiency in a decentralized regulation context: the case of the Italian integrated water service

The reformed Italian water and sewerage industry has several distinctive features. It is based on a decentralized structure where local authorities are entitled to define detailed long-term budget plans that claim to provide efficiency incentives to operating suppliers. Unlike previous studies, this paper analyzes the cost efficiency embedded in these budget plans to evaluate the actual capability of local regulators to adequately orientate firm performance. Several panel data cost frontier models were estimated that incorporate diverse specifications for inefficiency and unobserved heterogeneity terms. The results indicate that the decentralized planning mechanism applied in Italian water and sewerage industry regulation failed in fulfilling the declared goal and further highlights that the time-invariant terms are the prevailing source of cost differences, which may conceal a structural component attributable to persistent inefficiency.     

Food for Kids: How Children Influence their Parents Purchasing Decisions

During the last decades, sociological changes have modified the role of children within families: participatory models have become more widespread, to the detriment of more authoritative ones: this change has had consequences also in reference to families’ purchases. In scientific literature some scholars have shown that this influence is real, and marketers try to take advantage of this through a communication style that attempts to “teach” children how to pester their parents: this is the so-called nag factor. To understand which are the parental attitudes toward kids’ food products, a questionnaire has been administered in schools (nursery and primary) to a random sample of parents, representative of a larger sample of kids (200 in all). Findings showed that pestering is a real attitude, in particular among the littlest children. Moreover, these findings reflect in part the reality described by marketing literature: children influence the purchasing decisions of their parents, but this influence decreases when mothers and fathers are more aware of the importance of a quality-based diet.     

Towards democratic governance of uncertainty? Contesting notions of participation,control and accountability

Managing risk in international society has posed a new challenge not only to states and international organisations, but also to experts, scientists and citizens. It has generated a demand for new sets of laws, regulations, instruments and governing bodies to tackle various risks such as natural disasters, economic and financial crises, and unintended consequences of policy reforms. Accordingly, new modes of interactions between states, experts and citizens seem to be emerging across countries and in different high-risk sectors. Little research has been done to illuminate interactive and dynamic aspects of emerging governance and regulatory arrangements and their impact on participation, control and accountability in liberal democracies. This special issue has assembled research papers and commentaries from practitioners and academics which critically examine these themes and explore what future research on the ‘world risk society’ could offer to political science and beyond.     

Testing the expectations hypothesis of the term structure with permanent-transitory component models

This study proposes a new application of Permanent-Transitory Component Models (PTCMs) to test the Expectation Hypothesis of the Term Structure (EHTS). Unlike previous approaches, tests based on PTCMs can simultaneously detect departures from rational expectations and time varying term premia. We set out analytically and empirically the links across previous tests and PTCMs. We also show that PTCMs identify an additional restriction for rational expectations, on top of the one-to-one relationship between forward and spot rates, that must be imposed in estimations of term premia. Data for the short-end of the US term structure suggest that both factors contribute to the rejection of the EHTS. Moreover, the empirical estimates of term premia are persistent and exhibit sign fluctuations. Their stochastic properties depend crucially on whether the additional restriction for rational expectations is imposed in estimation.     

Bargaining Coalitions in the WTO Agricultural Negotiations

This paper aims to understand the structural features of bargaining coalitions in the Doha Round of the WTO. We provide an empirical assessment of the preferences of each negotiating actor considering general economics indicators, development levels, structure of agricultural sectors and trade policies. Bargaining coalitions are analysed by grouping countries using a cluster analysis procedure. The clusters are compared with existing coalitions in order to assess their degree of internal homogeneity as well as their common interests. Such a comparison allows the identification of possible ‘defectors’, i.e. countries that, according to their economic conditions and policies, seem to be relatively less committed to the positions of the coalition they join. In addition, the ex‐post analysis of the counterfactual coalitions sheds light on the ‘distance’ between different coalitions as well as between individual countries and the best alternative group available. Empirical results confirm our research hypothesis: clusters of structurally homogeneous countries well represent existing bargaining coalitions. In particular, the G‐20 shows a high degree of internal coherence, which, in our framework, may provide a clue to the ‘sustainability’ of this coalition and to its relevance in the Doha Round negotiations.     

Introduction: A New Architecture or New System? A Survey of International Monetary Reform in the 1990s

The international monetary system (IMS) is a macroeconomic concept that encompasses the foreign exchange-rate regulation, the capital movement system, and all “the rules of the game” for the adjustment of international payment imbalances. The international financial architecture (IFA) is, in contrast, a microeconomic concept and should not be considered synonymous with the IMS. The IFA is one element of the IMS. The current set of international monetary arrangements has been frequently called a “nonsystem.” Today there are two missing pillars in the reform efforts: a framework for managing the interdependence among the macroeconomic policies of the global powers (the United States, Europe, and Japan) and the market-oriented approach to the financing of the IMF.     

Hardened Budgets and Enterprise Restructuring: Theory and an Application to Romania

We identify the presence of soft budgets and analyze their impact on enterprise restructuring in Romania over the initial transition period. A simple analytical framework is developed to show that hardened budget constraints foster rationalization of costs but not new investment. The latter requires availability of external financing. The model emphasizes the importance of the credibility of hardened budgets and the empirical findings are consistent with its predictions. Using a sample of over 4000 Romanian enterprises from 1992 to 1995, we show that hardened budget constraints induce labor shedding. However, there is no evidence of new investments. J. Comp.

Testing for a break in trend when the order of integration is unknown

Harvey, Leybourne and Taylor [Harvey, D.I., Leybourne, S.J., Taylor, A.M.R. 2009. Simple, robust and powerful tests of the breaking trend hypothesis. Econometric Theory 25, 995–1029] develop a test for the presence of a broken linear trend at an unknown point in the sample whose size is asymptotically robust as to whether the (unknown) order of integration of the data is either zero or one. This test is not size controlled, however, when this order assumes fractional values; its asymptotic size can be either zero or one in such cases. In this paper we suggest a new test, based on a sup-Wald statistic, which is asymptotically size-robust across fractional values of the order of integration (including zero or one). We examine the asymptotic power of the test under a local trend break alternative. The finite sample properties of the test are also investigated.     

Habit formation and indeterminacy in overlapping generations models

I introduce habit formation into an otherwise standard overlapping generations economy with pure exchange populated by three-period-lived agents. Habits are modeled in such a way that current consumption increases the marginal utility of future consumption. With logarithmic utility functions, I demonstrate that habit formation gives rise to stable monetary steady states in economies with hump-shaped endowment profiles and reasonably high discount factors. Intuitively, habits imply adjacent complementarity in consumption, which in turn explains why income effects are sufficiently strong in spite of the logarithmic utility. The three-period horizon further strengthens the income effect.     

International Development Strategies of Luxury-goods Players in China

The aim of this paper is to study and analyse the intemationalisation strategies chosen by the main luxury-goods players in the Chinese market, demonstrating the business intemationalisation processes. The research questions are： ttow luxury companies have developed distribution strategies in the Chinese markets？ What are the main formats of distribution for the Chinese markets？ Are there any differences in the internationalization process between the main players of the luxury markets and the smaller ones？ The methodology is based on the analysis on multiple-case ~.nalysis on a sample of luxury-goods companies and identifies and compares the different strategies used by the players analysed. The research process starts from identifying and selecting the most well-known companies operating in the luxury branded sector, which have established a presence in the Chinese market with their own brand, collecting secondary data for the selected companies （website, corporate profile, articles on websites and in trade magazines and interviews with the management）, analysing the data collected and interpreting the main results to have emerged from the research. The main findings and conclusions are that the route to development in the Chinese market taken by the players in the luxury-goods sector, historically undertaken by delocalising production operations, has in recent years begun to accelerate with new forms in play, principally linked to distribution. The Chinese market tbr luxury brands is ever more an outlet market rather than a production hub. The ability to create brand awareness will become a key factor for successful consolidation of the competitive position in this market, an operation that can only be performed through distribution. Moreover, Chinese high-end consumers are becoming ever more demanding, seeking out an ever more sophisticated shopping experience. Just as happening in other markets, opening directly operated stores is a strategic choice for reaching and convincing end-consumers, sinc
