A government agency wants a facility to be built and managed to provide a public service. Two different modes of provision are considered. In a public‐private partnership, the tasks of building and managing are bundled, whereas under traditional procurement, these tasks are delegated to separate private contractors. The two provision modes differ in their incentives to innovate and to gather private information about future costs to adapt the service provision to changing circumstances. The government agency’s preferred mode of provision depends on the information‐gathering costs, the costs of innovation efforts, and the degree to which effort is contractible.  相似文献

Abstract

This article addresses how and to what extent a governance mode can legitimately provide public services. A single case study of the partially privatized Berlin Waterworks is used to analyse the level of input and output legitimacy as well as potential trade-offs between the criteria emerging in a public–private partnership (PPP) in the water supply and sanitation sectors. While the Berlin Waterworks as a PPP leads to a lower level of resource protection and public acceptance, it leads to a higher level of efficiency and profitability than under the previous public model.  相似文献

Teams need to pass through a series of development stages before they can operate effectively, and, in a changing context, it has also been demonstrated that teams need to continue learning in order to remain effective. This article aims to explore the relationship between team development and team learning. In particular, it focuses on when and why basic team learning processes such as sharing information, co‐construction, and constructive conflict occur during different phases of development. It can be hypothesized that although each stage of team development is characterized by specific learning tasks, team learning processes occur more in certain stages than in others. The results from a model‐based cluster analysis and ANOVA analyses on a sample of 44 professional teams show that team learning occurs more in the later phases of group development due to higher levels of team psychological safety and group potency.  相似文献

Using a sample of large US firms, this study shows that blockholders in combination with liquidity can contribute positively to innovation (R&D investments). We contribute to the literature on managerial myopia that has focused mainly on large owners and their type (short-term/long-term). Our results are in line with recent theoretical studies arguing that blockholders in combination with market liquidity can mitigate managerial myopia, as suggested by the exit model of governance. The results indicate that blockholders can be efficient in resolving agency problems and that they can enhance long-term prosperity, even when the individual blockholder investment horizon may not be long.  相似文献

Exploiting exogenous variation in childcare prices stemming from a childcare price reform, this paper estimates effects of reductions in childcare costs on female labour supply. The reform introduced a cap on childcare prices, and lead to considerable reductions in prices depending on family type and region of residence. Since the price is determined by a handful of observed characteristics, we are able to match households that are similar in all relevant aspects, but experienced quite different price changes. Our difference-in-differences regression matching estimates are very precise, and close to zero.  相似文献

This paper considers several methods of producing a single forecast from several individual ones. We compare “standard” but hard to beat combination schemes (such as the average of forecasts at each period, or consensus forecast and OLS-based combination schemes) with more sophisticated alternatives that involve dimension reduction techniques. Specifically, we consider principal components, dynamic factor models, partial least squares and sliced inverse regression.Our source of forecasts is the Survey of Professional Forecasters, which provides forecasts for the main US macroeconomic aggregates. The forecasting results show that partial least squares, principal component regression and factor analysis have similar performances (better than the usual benchmark models), but sliced inverse regression shows an extreme behavior (performs either very well or very poorly).  相似文献

ABSTRACT

Most visual package research in marketing to date tests only the main effects of certain visual package elements in artificially isolated experimental contexts, though, in the store, these elements are presented to the shopper in active visual circumstances. Most food packages are highly cluttered with a number of visual and text elements all competing for the shopper's limited attention; this calls into question the external validity, and therefore the usability for practitioner purposes, of these results. Given that marketers often rely on a single visual element as the sole carrier of some particular promotional message, it is critical to ascertain whether single visual elements can break through such visual clutter to effectively deliver their promotional messages to the shopper. In this study, we manipulate the level of background activity of packages while testing the ability of one visual package element—its overall shape—to affect one particular piece of package information of concern to food shoppers— appearance of size or volume. Surprisingly, our results show that the main effect of package shape type on volume perception not only remains robust under visually cluttered conditions, but that the effect is actually heightened for certain, more geometrically complex package shape types. Managerial implications are discussed.  相似文献

Despite growing research on ecotourism in Ghana, it is unclear to what extent colonial approaches to forestry and wildlife conservation still influence ecotourism in the country. This paper examines ecotourism development in Ghana from a postcolonialist perspective. It is based on a thematic assessment of primary data from in-depth interviews with a range of ecotourism actors. The paper shows that ecotourism in Ghana, much like colonial forestry and wildlife conservation, faces challenges such as the marginalisation of the local community, the use of neo-crisis narratives, a dependence on international forces, and the marginalisation of local ecological knowledge. It argues for a holistic approach to the development of ecotourism as a win–win strategy for sustainable development.  相似文献
