Firm-level interactions between exporting and productivity: Industry-specific evidence

This paper investigates interactions between exporting and productivity at the firm level, using a panel of firms in the UK chemical industry. This is both highly technology intensive and the UK’s largest exporting sector. We find exporters are more productive than non-exporters, but are also on average smaller. This superior productivity performance among exporters appears to be caused by both self-selection and learning-by-exporting effects. In contrast to other studies, we find learning effects are significantly positive among new entrants, weaker for more experienced exporters and negative for established exporters. JEL no.

城市商业中心地的形成与发展研究

在现实生活中,城市不同等级商业中心地的形成与发展主观上似乎遵循着某种规律,而客观上又呈现出无规则分布的特征.在城市不同等级商业中心地形成与发展过程中,有两个关键性因素,即交易成本和徒劳交易系数.这两个因素的变化情况,影响和制约了城市不同等级商业中心地的形成和发展.因此,在城市商业中心地的建设以及促进城市交易的活动过程中,节省交易成本支出、降低徒劳交易系数的制度安排、经营环境和信息流通空间就是非常重要的.     

Finding Pareto Optimal Insurance Contracts

This paper deals with on-line computation—or step-wise learning—of Pareto optimal insurance contracts. Our approach tolerates that the loss distribution might be unknown, intractable, or not well specified. Thus we accommodate fairly inexperienced parties. Losses are here simulated or observed, one at a time, and they cause iterated revisions of the premium. The mechanical and global nature of probability calculus thereby yields to more tentative, myopic procedures, possibly closer to how humans operate or reason in face of risk. Sequential revisions may also reduce the expense of insurers' time and money in seeking sufficient statistics. Emphasized below is the remarkable simplicity and stability of the resulting adaptive procedures. Special attention goes to catastrophic risks, and to subsidized or competitive insurance.
