This paper fits into the theoretical framework of service networks. Its aim is to understand service network change meaning, characteristics and connections with extant literature and to investigate how a service network can change in a specific context, a regulated sector. The regulated service network considered is the Italian health care network. A theoretical framework guided the analysis to explore how the actors' perceptions evolved during specific time, space, and relationship dimensions in terms of what, why and where changes happened, happen or will happen.  相似文献

The role of well-functioning markets for development is now widely recognized. However the challenge remains to make these markets benefit the poor and the environment. Increasing attention is being given to the potential role markets can play for agrobiodiversity conservation through product diversification and increasing competitiveness in niche and novelty markets. Several case studies were undertaken that explore the use of market-based approaches to on-farm agrobiodiversity management and livelihood improvement. This paper explores how the theory of collective action can provide a more synthetic understanding of how market chains operate, and the changes that could permit a more equitable distribution of benefits. The case studies illustrate the need for improved trust, mutual understanding of each actor’s involvement, and an agreed process of collective action with a high level of community participation. The cases differ in their degree of collective action, the level of market organization and the ways in which handling, processing, and innovative marketing add value to the agrobiodiversity products. Comparative analysis identified a range of situations in which market development can support agrobiodiversity conservation and livelihoods.  相似文献

There are many research on consumer perception of fish product attributes. To increase fish consumption, as recommended by international health organizations and dietary guidelines, there is a need to better understand what drives consumers to fish consumption behaviour. The objective of the research is to explore determinants of fish frequency consumption, with focus on healthy attitude and socio-demographic or family structure characteristics. The research interviewed 740 consumers face-to-face. Data elaboration includes a factor analysis, with PCA and Varimax rotation, and multiple multivariate linear regressions. Results show that consumer health-orientation and social influences are better drivers to increase fish consumption frequency, compared to socio-economic characteristics, including households with children. Easing consumer time constraints and fish purchasing favor convenience and at home fish consumption frequency. Given the health advantages of higher fish consumption, government initiatives should support fish food industry marketing strategies.  相似文献

This paper examines the interactions between Foreign Direct Investment (FDI), inequality, and growth, both from an empirical and a theoretical point of view. Using a panel of 119 developing countries, we observe that FDI promotes both inequality and growth, and tends to reduce the share of agriculture to GDP in the recipient country. We then set up a growth model of a dual economy in which the traditional (agricultural) sector uses a diminishing returns technology, while FDI is the engine of growth in the modern (industrial) sector. The main predictions of the model are consistent with the stylized facts observed in the data.  相似文献

We use the natural experiment of twins at first birth to estimate the effects of unplanned fertility on the nutritional status and school enrolment of children in Romania, a country with a unique fertility history. A first‐birth twins shock has negative impacts on children's human capital investments, particularly for later‐born siblings. We infer that harsh pronatalist policies prior to the 1989 Revolution had adverse consequences for the human capital of Romanian children, and that policies to make fertility control easier will have significant positive impacts on children's health and schooling.  相似文献

The internet has emerged as a widely recognised distribution channel for the banking industry in Europe. Traditional banks, as well as new players, have discovered its effectiveness compared with other channels. The aim of this paper is to draw a picture of online banking in Europe, by observing behavioural patterns of internet users accessing bank websites and managing their finances online. Similarities across countries as well as main differences emerge in market structure and competitive dynamics. In-depth analysis of Spain and Italy is provided.  相似文献

Following the rationale for regional redistribution programs described in the official documents of the European Union, this paper studies a simple multicountry model built around two regions: a core and a periphery. Technological spillovers link firms' productivity within each of the two regions, and each country's territory falls partly in the core and partly in the periphery, but the exact shares vary across countries. In line with the official view of the European Union, we find that the efficient regional allocation requires both national and international transfers. If migration is fully free across all borders, the optimal redistribution policy results from countries' uncoordinated policies. However, if countries have the option of setting even imperfect border barriers, then efficiency is likely to require coordination on both barriers and international transfers (both of which will be set at positive levels). The need for coordination increases as the Union increases in size.  相似文献

Borrowing from the experience of environmental markets, this paper proposes a system of tradable deficit permits as an efficient mechanism for implementing fiscal constraints in the European Monetary Union: having chosen an aggregate target for the Union and an initial distribution of permits, EMU countries could be allowed to trade rights to deficit creation. The scheme exploits countries' incentives to minimize their costs, is transparent and flexible in accommodating idiosyncratic shocks and allows for adjustments in case of Europe-wide recessions. In addition, it need not treat all countries identically and can be designed to penalize countries with higher debt to GDP ratios. Finally, the scheme rewards countries for reducing their deficit below the initial allowance, lending credibility to the Stability Pact's goal of a balanced budget in the medium run.  相似文献

Forecasting oil prices is not straightforward, such that it is convenient to build a confidence interval around the forecasted prices. To this end, the principal ingredient for obtaining a reliable crude oil confidence interval is its volatility. Moreover, accurate crude oil volatility estimation has fundamental implications in terms of risk management, asset pricing and portfolio handling. Generally, current studies consider volatility models based on lagged crude oil price realizations and, at most, one additional macroeconomic variable as crude oil determinant. This paper aims to fill this gap, jointly considering not only traditional crude oil driving forces, such as the aggregate demand and oil supply, but also the monetary policy rate. Thus, this work aims to contribute to the debate concerning the potential impact of (lagged) US monetary policy as well as the other crude oil future price (COFP) determinants on daily COFP volatility. By means of the recently proposed generalized autoregressive conditional heteroskedasticity mixed data sampling model, different proxies of the US monetary policy alongside US industrial production (proxy of the US aggregate demand) and oil supply are included in the COFP volatility equation. Strong evidence that an expansionary (restrictive) variation in monetary policy anticipates a positive (negative) variation in COFP volatility is found. We also find that a negative (positive) variation of industrial production increases (decreases) COFP volatility. This means that volatility behaves counter-cyclically, according to the literature. Furthermore, the out-of-sample forecasting procedure shows that including these additional macroeconomic variables generally improves the forecasting performance.  相似文献
