锦99块高含水期热采可行性研究

锦99块杜家台油层为注水开发的稠油油藏.常规水驱效果较差,水驱采收率仅为23.8%.高含水期,油层的平面及层间矛盾十分突出.针对该区块油藏特点和剩余油分布状况,利用蒸汽吞吐热采技术,以吞吐引效为主,解堵降粘为辅.累计油汽比达1.63以上,断块采油速度由0.48%上升到0.77%,累计增油8.96×104t,采收率提高至27.4%.     

锦607块地面集输工艺优化技术

锦607块地面集输工艺运用自动化平台计量、自控掺液、油气混榆、集中加热等新技术,形成了新的稠油区块地面油气集输模式,克服了传统平台井集输工艺存在的集油半径大、工艺复杂、工作量大、能源浪费严重问题,实现了减少地面建设投资、缩短集油半径、节能降耗的目的.其成功经验和管理模式,在油田集输工艺"优化、简化"工作上,具有十分重要的意义.

东晋南朝主要通货商探

东晋南朝时期商品经济日益发展，造成对货币的需求量日趋增长，而当时长期活跃在流通领域的主要通货是铜钱，其他诸如谷、绢或者金银、铁钱等的货币的功能都要当有限。这是研究这一时期官方屡禁不止的铜钱私铸、剪凿现象的一个必要前提。     

Market process(es) and (un)knowledge

By extending an underdeveloped idea of Lachmann, I show that the Austrian theory of the market process à la Kirzner is unable to explain the diversity of market processes because it neglects the imperfect inter-market mobility of factors of production. I show that by taking into account the imperfect mobility of capital equipment and the associated reshuffling costs, it is possible to formulate a set of empirically testable implications about the unfolding of the market process. Furthermore, I show that reshuffling costs shape the context in which the learning process takes place and that the epistemic assumption of structural opacity on which the Austrian theory of the market process relies is not incompatible with the epistemics assumption of structural transparency of neoclassical economics. These epistemic assumptions can be seen as the two poles of a “knowledge spectrum”, from potential omniscience to sheer ignorance.     

Dynamic adjustment and long-run equilibria: Panel data estimates for the East German states

The economic development in East Germany after unification shows both, success and failure. In the early nineties wages and productivity increased fast; later on catching up faded out. A central question from a policy viewpoint is whether this fading out indicates a reduction of the adjustment speed or an equilibrium gap. This points towards a stationarity analysis of differences between East and West Germany. Our paper presents panel data estimates for the East German states for wages, productivity, competitiveness and unemployment. The results reveal that the adjustment was fast, but the equilibrium gaps are large.     

Inflation adjustment in the open economy: an I(2) analysis of UK prices

This paper estimates a cointegrated vector autoregressive (VAR) model for UK data on consumer prices, unit labour costs, import prices and real consumption growth. The estimated VAR indicates that the nominal variables are characterised by I(2) trends, and that a linear combination of these processes cointegrate to I(1). This supports an analysis in which I(1) and I(2) restrictions are imposed. A key finding is that an increase in real import prices reduces productivity adjusted real wages, such that the change in domestic inflation is moderated. This may explain why the depreciation of sterling in 1992 left inflation unchanged.

东亚金融一体化程度与福利收益的实证研究

本文利用1970-2004年东亚国家和地区的相关数据,分析了以消费风险分担来衡量的东亚地区金融一体化的程度,以及东亚地区在实现完全风险分担后带来的潜在的福利收益.相比OECD国家和欧盟国家,东亚国家和地区风险分担的福利收益是比较高的,因此可以得出东亚国家和地区金融市场一体化应进一步深化,但在开放金融的同时应加强银行和金融市场监管的合作,以促进人民福利水平的提高的结论.     

Uncertainty and partial adjustment in double-auction markets

A model is presented of price determination in double-auction markets. The framework is contrasted with naive autoregressive models of price behavior. Implications of model choice are illustrated with the use of market experiments from several institutions.
