This article is based on research investigating why local authorities innovate and what happens when they do. The authors show how local authorities have responded to the current normative climate for innovation, and explore the interaction between central policy and local action. The article demonstrates the importance of the policy climate set by central government in fostering—or constraining—innovation at a local level. 相似文献

Agricultural trade impasses have again frustrated the GATT process. Interest in preferential/regional trading blocs is increasing. the paper probes the theoretical and empirical consequences of preferential arrangements instead of multilateral liberalization. It concludes that in a second-best world preferential arrangements could either improve or decrease global welfare. For agricultural trade, previous experience suggests that in regional groupings such as the EC trade diversion exceeded trade creation. This results from trade distorting domestic policies. Prospects for liberalization of agricultural trade under either GATT or preferential arrangements are limited. the consequences for small agricultural exporters are not positive. 相似文献

Prior to making important decisions, marketing managers go through an evaluation process in which available alternatives are
compared. Yet, no systematic discussion of the evaluation process exists in the marketing literature. This article reviews
the marketing and behavioral decision theory literature in order to identify factors that may cause errors in the two fundamental
elements of the evaluation process—the estimation of probabilities and the determination of the value of outcomes. Propositions
are developed that specify circumstances in which marketing management decisions may be influenced by judgmental biases, and
procedures are identified for debiasing such judgments. 相似文献

Sufficient conditions are found for designs, derived from completely symmetric designs by deleting binary blocks, to be E-optimal. Sufficient conditions are also found for E-optimality of designs obtained from other E-optimal designs by deleting all blocks forming a balanced incomplete block design on a subset of the treatments. The results include many binary and non-binary designs for which E-optimality was previously unknown. 相似文献

There is ongoing debate about the apparent weak or negative relation between risk (conditional variance) and expected returns in the aggregate stock market. We develop and estimate an empirical model based on the intertemporal capital asset pricing model (ICAPM) that separately identifies the two components of expected returns, namely, the risk component and the component due to the desire to hedge changes in investment opportunities. The estimated coefficient of relative risk aversion is positive, statistically significant, and reasonable in magnitude. However, expected returns are driven primarily by the hedge component. The omission of this component is partly responsible for the existing contradictory results. 相似文献

It is widely perceived that credit conditions for UK consumers, particularly in the mortgage market, have been radically liberalized since the 1970s. The implications for the housing market and consumer spending have been important. This article by John Muellbauer draws on a 1997 paper by the author which examined data from the Survey of Mortgage Lenders to learn, from information about loan-to-value ratios of first-time buyers, classified by region, about changes in mortgage credit conditions. By controlling for economic and demographic influences on credit conditions, a single time-varying index of mortgage credit conditions was extracted from these SML data. This index rises in the 1980s, peaking towards the end of the decade. It retraces part of its rise in the early 1990s before rising again by 1995 to a level not far below the previous peak. The article considers whether more recent data suggest a further liberalisation of mortgage credit conditions. It draws on joint research with others to discuss possible implications for consumer spending, house prices, the volume of property transactions and mortgage defaults. 相似文献

Human capital raises rural incomes, but this effect is swamped by higher returns to human capital in urban markets. This leads to "brain drain" from rural areas. Populations grow more rapidly in rural counties that have a diversified employment base. Farm population grows faster (or declines more slowly) in counties with relatively high farm income, and nonfarm populations grow faster in counties with relatively high nonfarm income. However, higher farm incomes lead to slower nonfarm population growth and vice versa. Rural county government services financed by local taxes or debt have neutral or negative effects on population growth. 相似文献
