Avoiding an ecological regime shift is sound economic policy
نویسنده
چکیده
We extend the shallow lake model by adding the capital stock of an industry. A government can mitigate the effects of pollution arising from industrial activities by imposing the requirement to abate emissions. Within this framework two scenarios are examined: in the social optimal benchmark, the social planner optimally allocates investment. In the competitive equilibrium, market forces determine the investment in capital, but the government can still abate emissions. We find that irreversible environmental regime shifts are avoided in the competitive equilibrium by means of a static level of abatement when it is socially optimal to do so. & 2013 Elsevier B.V.

Turning back from the brink: detecting an impending regime shift in time to avert it.
Ecological regime shifts are large, abrupt, long-lasting changes in ecosystems that often have considerable impacts on human economies and societies. Avoiding unintentional regime shifts is widely regarded as desirable, but prediction of ecological regime shifts is notoriously difficult. Recent research indicates that changes in ecological time series (e.g., increased variability and autocorrel...

Monetary policy is one way of controlling economic fluctuations, and in recent years, developing countries (including Iran) have been particularly concerned with policymaking. For this reason, it is necessary to consider how these policies will affect the Iranian economy and its variables. It should also be examined whether the existence of inflationary conditions in the Iranian economy can hav...
متن کاملIndicators of regime shifts in ecological systems: what do we need to know and when do we need to know it?
Because novel ecological conditions can cause severe and long-lasting environmental damage with large economic costs, ecologists must identify possible environmental regime shifts and pro-actively guide ecosystem management. As an illustrative example, we applied six potential indicators of impending regime shifts to S. R. Carpenter and W. A. Brock's model of lake eutrophication and analyzed wh...
