| Abstract: | Using a considerable number of theoretical and empirical sources, we analyze the relationship between democracy and environment. First, we compare the situation in democracies and non-democracies. Later, we discuss environmental distribution conflicts and the role of economic growth. In addition, we illuminate the way in which democratization influences environmental policies, concentrating on the role of economic inequality. Moreover, we discuss the impact of electoral rules and systems, as well as polluting lobbies. Finally, we consider political alternatives and sum up the main conclusions. |

| Abstract: | In hot, arid regions, yields are low and unstable, growing season limited to one. Greenhouses can stabilize and improve yields and extend seasons. But their adoption is impeded by the requirement of large amount of water for (evaporative) cooling. Arid Area Greenhouse (AAG) is being developed to reduce or eliminate this need by employing earth-tube-heat-exchanger (ETHE). A prototype AAG was installed in the year 2002 at village Kothara (ƒÚ 23¢X 14 N, ƒÜ 68¢X 45 E, at 21 m a.s.l.). AAG is of 20 X 6 X 3.5 m size. ETHE is buried 3m deep and coupled to AAG in closed-loop. ETHE provides 20 air changes per hour. There is provision of closable vents - two along the base of long sides and one along the ridge. A retractable shading curtain is provided over the roof. By now five rounds of cropping have been done. ETHE was able to heat the greenhouse from 9¢X C to 22-23¢X C in half hour in the cold winter nights. Static ventilation along with shading was effective for day time control till early March. Subsequently ETHE was operated. It limited the greenhouse temperature gain to just 2.5¢X C. Yield of tomato was 1.5 to 2 times, water used 44% of that in open-field. Water used was mostly for plants, only a small part was for foggers which were some times needed as supplement. ETHE and natural ventilation hold promise as environmental control devices for greenhouses in hot arid regions. |

| Abstract: | This article reviews issues related to the incorporation of non-renewable resources in the theory of economic growth and development. As an offshoot of the new growth theory of the last two decades a series of contributions have studied endogenous technical change in relation to resource scarcity. We discuss the main approaches within this literature and consider questions like: How is the new literature related to the wave of resource economics of the 1970s? What light is thrown on the limits-to-growth issue? Does the existence of non-renewable resources have implications for the controversies within new growth theory? |

| Abstract: | We develop theory and present a suite of theoretically consistent empirical measures to explore the extent to which market intervention inadvertently alters resource allocation in a sequentialmove principal/agent game. We showcase our approach empirically by exploring the extent to which the U.S. Endangered Species Act has altered land development patterns. We report evidence indicating significant acceleration of development directly after each of several events deemed likely to raise fears among owners of habitat land. Our preferred estimate suggests an overall acceleration of land development by roughly one year. We also find from complementary hedonic regression models that habitat parcels declined in value when the habitat map was published, which is consistent with our estimates of the degree of preemption. These results have clear implications for policymakers, who continue to discuss alternative regulatory frameworks for species preservation. More generally, our modeling strategies can be widely applied -- from any particular economic environment that has a sequential-move nature to the narrower case of the political economy of regulation. |
