汉简所见“私市”研究

以往学界在讨论边疆经济问题时,多就屯田、经济开发、商业贸易等问题进行具体研究,并将私市归纳到普通商业行为当中。结合出土汉简文献,以中央政府与地方的互动为中心,去探讨私市这一特殊的经济形式所反映的中央与边疆的互动关系:二者的互动从来就不是单向的,在边疆向心力的培养过程中,西汉政府处在“二律背反”的矛盾境地之中。

Impact of correlated private signals on continuous-time insider trading

A model of continuous-time insider trading in which a risk-neutral in-sider possesses two imperfect correlated signals of a risky asset is studied.By conditional expectation theory and filtering theory,we first establish three lemmas:normal corre-lation,equivalent pricing and equivalent profit,which can guarantee to turn our model into a model with insider knowing full information.Then we investigate the impact of the two correlated signals on the market equilibrium consisting of optimal insider trading strategy and semi-strong pricing rule.It shows that in the equilibrium,(1)the market depth is constant over time;(2)if the two noisy signals are not linerly correlated,then all private information of the insider is incorporated into prices in the end while the whole information on the asset value can not incorporated into prices in the end;(3)if the two noisy signals are linear correlated such that the insider can infer the whole information of the asset value,then our model turns into a model with insider knowing full information;(4)if the two noisy signals are the same then the total ex ant profit of the insider is increasing with the noise decreasing,while down to O as the noise going up to infinity;(5)if the two noisy signals are not linear correlated then with one noisy signal fixed,the total ex ante profit of the insider is single-peaked with a unique minimum with respect to the other noisy signal value,and furthermore as the noisy value going to O it gets its maximum,the profit in the case that the real value is observed.

The Resources, an Essential Element in the Relationship Between Public and Private

This paper＇s objective is to examine the relationship between public and private sectors through the mechanisms of public intervention in the market. With the financial and economic crisis of 2008, there has been a coordination of states （G20） for the implementation of affirmative action in order to support the international financial system. Our hypothesis is that resource dependence is the basis of all interactions between the public and private sectors. The fact that the public sector bails out private sector activity shows that it is beneficial to citizens through employment and taxes repaid by the company and all this contributes to social stability. Here we develop an argument in two phases. The first is to revisit the question of the relationship between the state and the market. The second part develops the hypothesis by focusing on the interdependence of resources. The theory of resource dependence often applied to international relations and inter-organizational business has allowed us to highlight the correlation between public and private sectors

Strategic Management Development From the State-Owned Company to the Private Company

The privatization of a firm entails a thoroughgoing process of reform that includes the introduction of new management practices. A review of the theoretical and empirical studies conducted allows us to confirm that a systematic analysis of the contextual, organizational and strategic factors that arise after a public company＇s privatization does not exist. This study explores the changes in strategic management that take place after a public company＇s privatization and proposes a theoretical global analysis model that facilitates their analysis. In order to confirm the theoretical propositions posed, the contemporary multiple case study was used as a research methodology. In particular, the changes experienced in the strategic management area in four privatized Spanish companies were investigated along the lines of a longitudinal analysis. The results of this study show that most theoretical propositions are confirmed or tend to be, according to the evidence shown by the firms in the sample. In addition, a comparative analysis of the different firms＇ behaviors by following the structure constructed on the basis of the three areas （strategies, objectives and organizational structure） leads to the conclusion that all these areas are relevant to the process of change in a privatized firm＇s strategic management.

Research Characterized the Physical Properties of Recycled Aggregate of Civil Construction Wastes

One of the big problems of the urban centres of the cities in Brazil is the growth of the generation of the Civil Construction Waste （CCW）. A disturbing concern for the public and private sectors is to find proper disposal of Urban Solid Waste （USW） in large cities, since suitable dumping sites for this waste are increasingly scarce due to the spread and development of large urban centres. In general, recycling is currently one of the procedures most studied by researchers for disposal of such waste. In this context and aiming a new application for recycled CCW aggregates, the research characterized the physical properties of the material to use in fill compaction piles in soil improvement. The analysis shows results from laboratorial tests executed in CCW recycled samples, which came from works in different construction stages from Recife-PE, and natural aggregate, adopted as a reference. Characterization tests were performed with samples CCW recycled CLue aggregates and samples of natural fine aggregate （stone powder）. The results of characterization tests showed similarities between the CCW samples tested and the reference samples, indicating that the civil construction wastes has potcntial use as material for consolidation piles in foundation works.

A Need to Innovate the Dutch Building Regulation

In 2008, two governmental committees presented their conclusions on strengthening the role of the private building sector in building control. In 2011, three new studies were commissioned by the government to address perceived problems. One of them was an integral study, executed by ERB （Foundation Expertcentre Regulations in Building）, RIGO （Research Institute for Real Estate） and TNO （Research Institute for Applied Technologies）, to innovate the whole building regulations system. It led to proposals to redefine responsibility and liability for all parties. This study states that by an effort of yearly ￡100 million, unnecessary costs up to ￡l billion can be avoided and a real quality push will take place in the building and real estate markets. The goals to reach are to minimize the administrative burden for the building owner and to enforce the construction industry to build conforming to the regulations. This paper discusses the ERB study and the given proposals. The ERB study demonstrated that a quality push is needed which potential will lead to less costs for building owners. It also shows that proven solutions, part of the regulations, might be of help for all parties involved.

Driving Forces of Private Equity Investment in China： Case Studies of Private Entrepreneurship

In search of private equity investment opportunities in China, one would be astonished by the rise of raw private entrepreneurship in this largest emerging market economy in the world. The country is experiencing a transition from a planned, socialist economy to a market or mixed economy. The emergence of a significant private sector is one of the most important developments of the market-oriented reforms in China over the last quarter of a century. It is true that the transformation of public ownership into private ownership indeed gave a rise to the new private enterprises. Nevertheless, there is also an origination process of genuine private enterprises parallel to this privatization approach. In this paper, the concept of raw entrepreneurship is introduced to distinguish new, green-field private firms from the rest of the private sector that has emerged from older firms that have been converted from SOEs （state-owned enterprises） or COEs （collectively-owned enterprises）. It is also a concept that stresses the highly innovative manner in which private firms have emerged in China. This paper will explore deeply the concept of raw entrepreneurship through three case studies as well as theoretical analysis based on traditional wisdom.

Private equity＇s PRC Potential

he private equity （PE） bubble could be about to burst. During the market boom of the past few years, most bonds for funding leveraged buyouts （LBOs） were issued at low interest rates and few covenants. Since the collapse of the US sub-prime mortgage cri- sis, global markets have tightened considerably. I believe that the US io-year treasury bond yield will normalize back to 6% and the risk premi- um on bonds will also normalize. The interest rate on bonds for funding LBOs could increase by 4-5 percentage points from the bottom. Such an increase in funding costs would make most LBOs impossible.

Sustainable Management of Conurbation Forests in Northern Hesse (FRG)

Today 42% (9 000 km2) of the area of Hesse is covered with forests. The total area of forests hasslightly increased since several years. But actually the forests adjacent to the conurbations of NorthernHesse in the vicinity of Kassel in particular and in the Rhein-Main Region surrounding Frankfurt are in a verydifficult position. There is big demand for land to be converted into settlements, infrastructure, etc., whilethere is increasing need for the protective and recreational functions of the forests. Therefore maintenance ofexisting forests and establishment of new forests are amongst the most important responsibilities of theforest authorities on regional and district level.
