Considerable evidence from different countries has revealed important shortcomings in most road public–private partnership (PPP) models. In this paper a new PPP model is presented that overcomes some of the problems found in PPP road contracts. The new model is based on separating user tolls from the fees paid to PPP contractors and setting up new institutional arrangements to oversee PPPs. 相似文献

The objective of this paper is to explain geographical divergences in interest rates on personal loans to households using aggregated consumer knowledge-related metrics as predictors. The researchers quantitatively test their approach in countries in the Eurozone and in the Italian and Spanish regions. Social expertise explains between 69% and 84% of variance in household loan market prices at an international and inter-regional level. The approach taken is tested using real market data established after real service encounters and not published or recommended prices. 相似文献

Tourism is a very important tool for economic development. However, its economic effects are mainly conditioned by the level of leakage. This work defines leakage, provides an original evaluation of the entrepreneurial environment in showing that it is the one with the lowest level of leakage, and creates a new framework. It also measures leakage in an innovative way using a quantitative approach. In addition, the paper explores and shows how leakage can affect critical business factors, such as customer and employee satisfaction. The empirical study uses structural equations and data from hotels in the Valencian Region (Spain) to show how important leakage is in making businesses more competitive. The results confirm the new model and are of interest for company managers and public organizations. 相似文献

The potential contributions of new biotechnologies to sustainable food and income security have been the subject of widespread discussions around the turn of the 21st century. But distributional issues of which segments of adopters of genetically modified (GM) crops benefit the most have not been given ample attention). Using propensity scores, we apply the (a) stratification‐multilevel method of estimating heterogeneous treatment effects; and the (b) matching‐smoothing method of estimating heterogeneous treatment effects proposed by Xie et al. We find that the incidence of higher yields, lower insecticide use, and reduced seed utilization in the Philippines diminishes progressively as a farmer's propensity to adopt Bt corn increases. Farmers with a low propensity to adopt Bt are those who farm smaller, nonirrigated farms located farther from seed suppliers and farmers without previous training on pest identification. In most cases, while these farmers are typically poorer farmers in smaller parcels, cannot afford irrigation and are situated in remote areas away from easily accessible seed suppliers, there is no evidence, however, that profits differ across farmers with varying propensities to adopt the Bt variety. 相似文献

The Albanian health care system is currently in a period of deep transformation as well as the country is reflecting the future reforms after the turbulent development of the most recent years. The admission of Albania among future members of the European Union requires also an innovation in the health care system in order to build a model more compliant with the European performance and standards. These innovations are required also in the managerial approach to the health care and in its financing system. The aim of this paper is to analyze the actual financing model of the Albanian health care sector while highlighting the possible future managerial development. First of all, this article presents a history review of the Albanian health-care system, analyzing the current governance model. The goal of this approach is to describe the starting point of the reform paths for the future policy makers. Afterwards the research underlines the transition from a financing model based on historical public expenditure to a system based on the performance as one of the main innovation in the managerial approach to the health care. The introduction of management thinking will then allow developing a cost-based financing model, an accounting system in the teaching hospital and, finally, a financing system able to pay for services provided by private health care entities. The article then offers also a contribution to policy makers in order to define the "paths" of the Albanian health care system in the next years. 相似文献

The existence of parallel economies that operate in the shadows of informality within most Latin American countries is widely recognized by the economic literature. However, its composition, size and effects on economic growth are still open questions. In this paper, we estimate the size and the evolution of the Mexican informal economy in the last three decades using a vector error correction model. In addition to the standard explanatory variables traditionally used in the currency demand approach, we include remittances given their relevance in the Mexican economic system. The results indicate that informality prior to the late 1980s accounted for at least two thirds of GDP, while stabilizing around one third of GDP in the last decade. Furthermore, our estimates provide evidence of a positive long-run relationship between informality and economic growth. 相似文献

This paper analyzes, in the context of negotiation, the problem of coordination and conflict resolution between the manufacturer
(Seller) and the retailers (Buyers) for a two-tier inventory system. The retailers capture demand (from customers) and therefore
are responsible for the level of service offered by the system. The larger the inventory that a retailer has of a particular
product, the lower the probability of running out of stock and therefore, avoid the possibility of a lost sale for the manufacturer.
A conflict arises (and therefore the negotiation process starts) when the manufacturer wants the retailer to increase the
level of service while retailers are satisfied with the status quo. Using the Nash bargaining solution, we develop a theoretical
framework that incorporates behavioral dimensions and predicts the outcome of “sharing” the profit. The results indicate the
advantage of developing long term relationships among the members of the distribution channel to minimize the uncertainty
and therefore the source of conflict. 相似文献

This paper extends existing insurance results on the type of insurance contracts needed for insurance market efficiency to a dynamic setting. It introduces continuously open markets that allow for more efficient asset allocation. It also estimates the role of preferences and endowments in the classification of risks, which is done primarily in terms of the actuarial properties of the underlying risk process. The paper further extends insurability to include correlated and catastrophic events. Under these very general conditions the paper defines a condition that determines whether a small number of standard insurance contracts (together with aggregate assets) suffice to complete markets or one needs to introduce such assets as mutual insurance.
