We provide a general condition under which consumption can be sustained indefinitely bounded away from zero in the continuous time Dasgupta–Heal–Solow–Stiglitz model, by letting augmentable capital substitute for a non-renewable resource. The assumptions made on the production function are mild, thus generalizing previous work. By showing that Hartwick?s rule minimizes the required resource input per unit of capital accumulation, and integrating the required resource input with respect to capital, we obtain a complete technological characterization without reference to the time path. We also use the characterization result to establish general existence of a maximin path. 相似文献

Raising the bar (5). Spatial Economic Analysis. This editorial summarizes and comments on the papers published in this issue 12(1) so as to raise the bar in applied spatial economic research and highlight new trends. The first paper examines the impact of the level of education on the decision to migrate and finds that it is approximately twice as large if both variables are modelled simultaneously. The second paper is one of the first papers to introduce a spatial component to models of international environmental agreements and to develop an exciting overlap with New Economic Geography. The third paper provides a tool, applied to Beijing, with which urban economic planners can investigate the role of variation and selection mechanisms in cluster development and identify possible paths of growth. The fourth paper contributes to the existing literature on retail geography by examining the role of consumption possibilities as an urban amenity. The fifth paper develops a Bayesian estimator of a linear regression model with spatial lags among the dependent variable, the explanatory variables and the disturbances. Finally, the sixth paper develops a semi-parametric generalized method of moments (GMM) estimator for a spatial autoregressive model with space-varying coefficients of the explanatory variables and a spatial autoregressive coefficient common to all units. 相似文献

Simulations with dynamic, single country, CGE models typically imply that reductions in domestic demand, e.g. a cut in investment, generate increases in exports and reductions in imports facilitated by real depreciation. However, currently in the U.S. a large reduction in investment is occurring simultaneously with a contraction in exports and little movement in the real exchange rate. We show that to describe this situation it is necessary to drop the standard CGE assumption that capital is always fully employed in every industry. After introducing an excess capacity specification, we simulate the U.S. recession with and without the Obama stimulus package. 相似文献

This paper positions sustainable mass tourism (SMT) as the desired and impending outcome for most destinations. Natural resource scarcity, development of green technology, climate change awareness, the global financial crisis, institutionalised environmentalism and Internet technology all facilitate the emergence of sustainability as a societal norm that is combining with the longer established norm of growth desirability. SMT convergence is occurring along three distinctive paths in an evolutionary manner that reflects environmental pragmatism. The market-driven ‘organic’ path describes the conventional tourism area life cycle model of Butler, whilst the regulation-driven ‘incremental’ path entails deliberate alternative tourism (DAT) in which carrying capacities are gradually increased to accommodate higher visitation levels. The hybrid ‘induced’ path describes planned mega-resorts conceived as growth poles. Each model is invested with its own specific planning and management implications. 相似文献

Environmental degradation and extractive industry are inextricably linked, and the industry’s adverse impact on air, water,
and ground resources has been exacerbated with increased demand for raw materials and their location in some of the more environmentally
fragile areas of the world. Historically, companies have managed to control calls for regulation and improved, i.e., more
expensive, mining technologies by (a) their importance in economic growth and job creation or (b) through adroit use of their
economic power and bargaining leverage against weak national governments, regional and international regulatory bodies. More
recently, the industry has had to contend with another set of challenges that involved treatment of indigenous people and
their traditional land rights, fair treatment of workers, human rights abuses, and bribery and corruption involving local
officials and political leaders. These challenges currently fall outside the traditional areas of regulation and control.
Nevertheless, they pose serious threat to the industry’s business practices because of their global scope, threat to company’s
reputation, and long-term risks of political instability leading to increasing cost of capital. Industry has responded to
these challenges by creating voluntary codes of conduct that would signify their intent to comply with higher standards of
conduct, and assuage public opinion that no further action is called for. These codes, however, lack any monitoring mechanism
and reporting integrity to assure the public that the industry members are indeed meeting their commitments. Consequently,
pressure on the industry continues unabated and with ever increasing calls for mandatory regulation and oversight. This article
examines the activities of one mining company, Freeport-McMoRan Copper & Gold, Inc., which has taken a radically different
approach in responding to these challenges at its mining operations in West Papua, Indonesia. While cooperating with industry-based
efforts of voluntary codes of conduct, Freeport also initiated a radically different response through its own voluntary code
that would directly focus on issues of human rights, treatment of indigenous people on whose traditional land its mine was
located; economic development and job creation and, improvements in health, education, and housing facilities, to name a few.
Additionally, the company earmarked large sums of money and involved representatives of the indigenous people in their management
and disbursement. The company took an even more radical action when it committed itself to independent external audits of
the company’s compliance with the code, and that these findings and company’s responses would be made public without prior
censorship by the company. We analyze the nature of corporate culture, vision and risk-taking propensities of its management
that would impel the company to embark on a high risk strategy whose outcomes could not be predicted with any degree of certainty
before the fact. The parent company also had to confront discontent among the management ranks at the mine site because of
cultural differences and management styles of expatriates and local (Indonesian) managers. Finally, we discuss in some detail
the extensive and intensive character of a two phase audit conducted by the outside monitors, their findings, and the process
by which they were implemented and reported to general public. We also evaluate the strengths and challenges posed by such
audits, their importance to the company’s future, and how such projects might be undertaken by other companies. 相似文献

Using a sample of 3808 firms from 1996 to 2007, the impact of three strategic options that can be implemented by local Asian (i.e., Indian) firms facing increased import competition in their domestic market is analyzed. On average, firms with greater investments in intangible resources and tighter product focus do better, while firms with greater international sales perform poorly compared to their peers. However, in industries characterized by high import competition, firms with international operations and product focus tend to have higher performance, while firms with intangible resources perform poorly. 相似文献

This paper compares the perceptions of marketing research executives and industrial respondents regarding factors impacting on industrial mail survey response. Following a review of the different research traditions to the study of mail response rates, a “survey‐on‐surveys “ approach is introduced and used to study the potential impacts of different design and implementation factors on survey response. The results of the study provide empirical evidence on the perceived influence of a wide variety of response‐inducing factors in industrial mail surveys, and are used to generate managerial recommendations for the conduct of the latter. Directions for future research are also identified. 相似文献
