Why does the rate of population growth decline in the face of economic growth? We show that growing product variety may induce a permanent reduction in the demand for children and a continuous rise in income and consumption.  相似文献

We show, within a single industry, the possibility that R&D‐investment is non‐monotonically related to competitive toughness: increasing when competition is soft and decreasing when competition is tough. This possibility results from the combination of a Schumpeterian markup squeezing effect discouraging innovation, and a concentration effect spurring innovators. It is obtained in a sectoral model where the number of innovators is random and where non‐successful investors may remain productive. The result is extended to a multisectoral stochastic endogenous growth model with overlapping generations of consumers and firms, the number of which is endogenously determined in the capital market.  相似文献

While the literature shows that perks can affect firm values positively or negatively, we argue that firms with higher perks are more likely to be associated with a lower quality of financial reporting, which, in turn, can affect the informativeness of stock prices. Based on hand-collected data on perks from Chinese listed firms, we find that firms with lower perks are associated with higher informativeness of stock prices (or lower R-square). Moreover, the positive association between perks and R-square is shown to be weaker for firms with higher financial reporting quality through audit and earnings quality measures.  相似文献

This paper examines the impact of Newsweek's ‘The Greenest Big Companies in America’ on stock values for large companies. Newsweek ranks the biggest Companies in America from one to 500. An event window of ten days following the rankings release to the public was examined to analyze the impact of relative rankings on stock values. Dummy variables were constructed denoting firms ranked in the highest and lowest quartiles. Control variables included return to the Dow Jones Industrial Average, the firm's beta coefficient and total revenue. The main finding of the study is that inclusion in the top quartile of the rankings has a positive and statistically significant impact on firms' stock values, while the coefficient for the lowest quartile was not statistically different from zero. The results provide evidence of a positive impact on stock values from favorable environmental recognition but no effect for low ranked firms.

Consistent with the challenges of sustainability science, land architecture offers a comprehensive approach to land system dynamics useful for numerous types of assessments, ranging from the vulnerability of coupled human–environment systems to forest transitions. With antecedents in several research communities, land architecture addresses the tradeoffs within and between the human and environmental subsystems of land systems in terms of the kind, magnitude, and pattern of land uses and covers. This approach is especially cogent for changes in tropical forests, given the broad-ranging forces acting on them and the equally broad-ranging consequences of their loss. The rudiments of the land architecture approach are illustrated for changes in seasonal tropical forests in the southern Yucatán of Mexico, the pivot of which is the Calakmul biosphere reserve. Simplifying the dynamics involved, the region-wide land architecture is the collective design of stakeholders with different land-use goals that favor tradeoffs in subsystem outcomes serving better either the reserve and related programs or the smallholder farmers that populate the region. A major tradeoff involves forest cover per se, which holds implications for forest transition theory. Evidence for an incipient transition involves the scale of analysis taken. The dynamics involved hold too much uncertainty to forecast a permanent transition to more forest cover and imply that more complex but robust versions of the theory are required.  相似文献

This paper analyses the financial and economic costs and benefits of the large scale National Ecological Network (NEN) nature conservation project in the Netherlands, taking into account transaction costs and land market impacts of different institutional arrangements. The net financial costs associated with achieving the current plan are equivalent with an annual amount €876 per hectare. Of the costs, transaction costs amount about 16% or €140 per hectare. The substantive land purchases involved in the plan will lead to land price increase of 20%. Nature management by agriculture turns out to be a relatively cheap option.  相似文献

The aim of this paper is to describe the rent control system in Sweden, evaluate the effects on consumption and production in the housing market, and provide a public choice explanation of the present rent control system.The first section of this paper contains introductory remarks and an overview of the rental market in Sweden. The Swedish rent control system and its prerequisites are described in section 2. Attention is given to two important prerequisites: the existence of a large municipal housing sector and a strong tenants' movement. As a result, a rent system has been developed with all rents set by negotiations. The rent structure is determined by a fairness principle, which has some resemblance to market adapted rents. The rent level will be determined by a non-profit condition in municipal housing companies.In section 3 the effects of the existing rent control system are discussed with the municipality of Stockholm as a test case. Effects on rent level and rent structure are evaluated, and the relation between rent policy in municipal housing companies and resulting rents in private housing is analyzed. Gains and losses to tenants and landlords are evaluated as well as effects on construction and maintenance.In section 4 a political perspective is discussed. The aim is to explain why the system is not implemented in the market adapted way it was intended. Finally, the future of the rent system is discussed.  相似文献

This paper investigates changes in factors bearing on technology adoption decisions in small manufacturing firms. It is hypothesized that, as a firm's experience with technology increases and its technological capabilities grow, the decision process is gradually modified and puts more weight on those factors which are more closely related to the true potential of the technology. An empirical study shows the more innovative firms to have an outward orientation dominated by clients and suppliers, and to pay more attention to the added flexibility brought about by new technology. It is also shown that functional groups within the company play a more important role in the decision-making process.  相似文献
