Fixed capital and internal rate of return

For a neo-Austrian process of production, more generally multisectoral fixed capital models, it is shown that the maximum rate of growth and the minimum rate of interest are both equal to the internal rate of return. This von Neumann type equality is here obtained in absence of truncation, i.e., free disposal of fixed capital. If several internal rates of return coexist, the economically significant one is the maximal one. This result provides theoretical grounds for the internal rate of return criterion in infinite horizon.     

Managing asymmetries in information flows and interaction between R&D,manufacturing, and service in complex product development

Studies of new product development have demonstrated the value of effective interaction between research and development (R&D) and manufacturing, but few studies also include service operations despite their growing importance. Building on in‐depth studies of two firms in the capital goods sector, the paper illustrates how the structural differences between the R&D‐manufacturing and R&D‐service interfaces result in serious information and interaction imbalances, and presents managerial means to handle these. The paper makes three contributions. First, it shows the value of moving beyond a dyadic perspective to studies of more complex structures involving triads of specialized functions. Second, the paper underlines the role of informational flows that can compensate for asymmetries in such triads and facilitate thoughtful trade‐off decisions. Third, the paper highlights the importance of creating conditions for integrated knowledge‐based approaches across functions, which involve the generation and sharing of new knowledge. The paper ends with an emerging management agenda to support such integrative efforts in complex product development projects.     

Education and early career outcomes of second-generation immigrants in France

We estimate a flexible reduced form dynamic model of schooling choices and labor market outcomes in France. Our analysis focuses on the comparison between second-generation immigrants and their French-natives counterparts. We show that the gap in higher education attainments between those two sub-populations is mainly explained by parents' background, and that schooling investment is the main determinant of the gap in permanent employment. After conditioning on schooling and observed characteristics, we find that ethnic origin explains less than 6% of the gap in access to permanent employment. A test of equality of counterfactual probabilities of accessing permanent employment across ethnic groups (measured at identical individual characteristics) typically fails to be rejected.     

家族企业要行使好所有权

那些能够延续三代或三代以上的家族企业,往往比其他同类企业更具竞争力。＂家族＂的两个难题家族企业往往是一种被忽略的所有制形式。然而,家族企业无所不在：从社区周围的夫妻店,到数百万支撑众多经济体的中小型企业,再到宝马、三星和沃尔玛等家喻户晓的巨头,到处都能见到家族企业的身影。     

STOCK‐FLOW INTERACTIONS,DISEQUILIBRIUM MACROECONOMICS AND THE ROLE OF ECONOMIC POLICY

This paper presents the ‘KMGT’ (Keynes–Metzler–Goodwin–Tobin) portfolio model and studies its stability properties. The approach to macrodynamic modelling taken here extends the KMG model of Chiarella and Flaschel (2000) , focusing in particular on the incorporation of financial markets and policy issues. The original KMG model considered three asset markets (equities, bonds and money) but depicted them in a rudimentary way so that they had little influence on the real side of the model. The only financial market influencing the real side of the economy was the money market (via an LM curve theory of interest). Here Tobin's portfolio choice theory models the demand for each asset in such a way that the total amount of assets that households want to hold equals their net wealth, which is a stock constraint attached to portfolio choice. There is also a flow constraint, that the net amount of assets accumulated (liabilities issued) by one sector must equal its net savings (expenditures). The Tobinian macroeconomic portfolio approach characterizes the potential for financial market instability, focusing on the interconnectedness of all three markets. The paper goes on to study the potential for labour market and fiscal policies to stabilize unstable macroeconomies.
