Cooperation and collaboration between companies represents a key issue within the conceptual framework developed by the IMP Group. However, little attention has been paid to a phenomenon which can result from such collaboration, i.e. collective action. This involves cooperative activities...

The growing specialization of firms and the reinforcement of vertical disintegration have led to an increasing reliance on purchasing and supply management. This means that an increasing proportion of value is created outside the boundaries of the firm, namely by suppliers. In this context, the...

This study makes two main contributions to the literature. Firstly, it tests empirically the relative timeliness of accrual measures and earnings components used as explanatory variables in accrual models (“accrual drivers”) regarding the impact of conservatism. Secondly, taking into account...

In this paper we analyze firms’ earnings management behavior to avoid losses conditional on the (asymmetric) incentive underlying market (positive/negative) returns. Our intuition is that firms with negative returns in the period (bad news, BN) face a higher incentive to undertake earnings...

In this paper we compare the costs of two regulatory policies about the entry of new firms. We consider an incumbent firm that has more information about the market demand than the regulator. Then, the incumbent firm can use this advantage to persuade the regulator to make entry more difficult....

Deep changes characterize the evolution of the Portuguese labor market concerning the average schooling of workers, particularly since the 1980s. The purpose of this paper is to investigate the consequences of those changes in the gender wage gap. In particular, we analyze and compare the way...

The asymmetric recognition of gains and losses underlying conservative accounting is not taken into account by Jones (1991)-type accrual models. Recently, Moreira (2002) and Ball and Shivakumar (2005a) have proposed piecewise linear accrual models designed to control for this asymmetric impact....

The paper tests whether human capital is a relevant foreign direct investment (FDI) determinant. Drawing on a large-scale survey of firms located in Portugal, and controlling for firms’ structural (i.e. size, age and industry), strategic (R&D and export intensities) and linkages (density of...
