Effects of extent and diversity of alliancing on innovation: the moderating role of firm newness

The purpose of this paper is to show the varying effects of alliance portfolio size and heterogeneity on innovation in biotechnology firms. Previous literature has indicated that the number and heterogeneity of partners in an alliance portfolio might have positive effects on innovativeness. Yet, engaging in multiple and heterogeneous collaborations also raises managerial costs and complexity levels disproportionally, potentially causing detrimental performance effects. Analysis of a unique panel dataset suggests that engaging in many alliances generally has a positive influence on a firm’s innovation output. Furthermore, maintaining diverse alliance portfolios and a high extent of alliancing jointly affects a firm’s innovation output ?negatively. By additionally showing that younger firms benefit disproportionally from both alliance portfolio diversity and size, this study provides a more nuanced view of alliancing effects.     

The role of planning in achieving indigenous land justice and community goals

This paper suggests that the capacity of indigenous groups to engage effectively in a range of planning activities is crucial to achieving land justice and community goals. This argument is relevant in the face of long-standing tensions between indigenous peoples residing in post-settler societies and nation-states such as Australia, Canada, and New Zealand over questions of land and natural resource use. The paper argues that effective planning is crucial for (i) protecting indigenous interests by engaging the planning activities of the state, (ii) the successful acquisition of lands through legal land claim processes, and (iii) helping indigenous communities achieve their goals by implementing effective community-based planning processes.     

WHAT DO CITIZENS THINK ABOUT PUBLIC ENTERPRISES? SUBJECTIVE SURVEY DATA ON THE LEGITIMACY OF THE ECONOMIC ACTIVITIES OF THE GERMAN PUBLIC SECTOR

We analyse the legitimacy of public enterprises that perform economic activities by focusing on the citizens’ subjective preferences, i.e. determining their political legitimacy. Using data from a representative survey conducted among 318 citizens of the German state of Rhineland‐Palatine, we explore determinants for the support of either privatisation efforts or the instrumental thesis, a widespread principle in German‐speaking countries, which considers public enterprises solely as instruments to fulfil economic policy objectives. Our results indicate that the respondents’ perception of the efficiency of public enterprises as well as their personal economic situation are important factors for the support of privatisation. The influential factors for the use of public enterprises as policy instruments are political ideology, the perception of a higher security of supplying goods and services as well as opinions regarding corporate social responsibility. The subjective preferences of a (democratic) country's citizens are thus an important reason why the public sector should or should not play an active part in providing goods and services. This can play an important role when decision makers from the public sector are keen to take into account the citizens’ approval or disapproval of privatisation measures.     

Jackknife estimation of stationary autoregressive models

This paper explores the properties of jackknife methods of estimation in stationary autoregressive models. Some general results concerning the correct weights for bias reduction under various sampling schemes are provided and the asymptotic properties of a jackknife estimator based on non-overlapping sub-samples are derived for the case of a stationary autoregression of order p$p$ when the number of sub-samples is either fixed or increases with the sample size at an appropriate rate. The results of a detailed investigation into the finite sample properties of various jackknife and alternative estimators are reported and it is found that the jackknife can deliver substantial reductions in bias in autoregressive models. This finding is robust to departures from normality, ARCH effects and misspecification. The median-unbiasedness and mean squared error properties are also investigated and compared with alternative methods as are the coverage rates of jackknife-based confidence intervals.     

外出务工对流出地家庭生计策略的影响——来自西部山区的证据

本文首先基于可持续生计框架,引入劳动力迁移的视角,之后改进农户模型以分析劳动力外出务工对流出地家庭生计策略的影响机理,并利用陕西秦岭北麓地区1074户的调查数据进行验证。结果发现:外地打工虽然有利于家庭的资本积累,但会阻碍流出地非农生计活动的参与和劳动力供给;本地打工在促进资本积累的同时,对参与林(经济)作物种植、养殖和自营等生计活动有显著的促进作用,但过多的劳动力外出务工仍然会减少本地其它活动的收入水平。     

Warum Vertrauen wichtig ist — Der ökonomische Blickwinkel

Die Finanzkrise hat die ?ffentliche Aufmerksamkeit auf eine der Grundstützen des marktwirtschaftlichen Systems gerichtet: das Vertrauen der Marktteilnehmer untereinander. Friedrich L. Sell und Marcus Wiens erl?utern die verschiedenen Sph?ren des Vertrauens (Zweierbeziehung, Gruppe, gesamte Gesellschaft), welche Risiken mit dem Vertrauen verbunden sind und wie diese überwunden werden k?nnen.
