A Java Reference Model of Transacted Memory for Smart Cards

Transacted Memory offers persistence, undoability and auditing. We present a Java/JML Reference Model of the Transacted Memory system on the basis of our earlier separate Z model and C implementation. We conclude that Java/JML combines the advantages of a high level specification in the JML part (based on our Z model), with a detailed implementation in the Java part (based on our C implementation)

The Impact of the Sarbanes-Oxley Act (SOX) on the Cost of Equity Capital of S&P Firms

This study examines the impact of SOX on the cost of equity capital for small and large S&P firms. The provisions of SOX aim to improve internal control systems and reduce information asymmetry by improving corporate governance systems and increasing transparency. Using a fixed-effects regression model, our findings suggest that the cost of equity capital has decreased post-SOX for the overall sample of firms, but more specifically for the small firms, which are usually associated with poor internal control systems and high information asymmetry. Collectively, our results provide evidence that SOX has had a positive impact on firms

Creative industries

Creative industries are nowadays central in many policies to stimulate the economic development of cities, regions and advanced capitalist economies in general. This paper contributes to the� creative industries literature in two respects. First, we empirically explore if high shares of creative industries in regions go together with one particular aspect of regional economic development, namely firm entry rates. Drawing on Dutch trade register data over a six-year period, it is concluded that at the level of municipalities there is indeed a connection between the share of creative industries and firm entry, even after controlling for the sizes of municipalities, and no matter if creative industries are defined broadly or narrowly. Second, the paper analyses if firms in creative industries are heterogeneous in terms of business processes and their contribution to regional firm entry. Drawing on previous work four creative domains are identified: arts, media and entertainment, creative business services and, at the periphery, knowledge intensive business services. After analysing survey data of 4,746 Dutch SMEs, we find that firms across these domains are distinct in their use of the surveyed business practices: innovation, strategy and marketing, and human resources practices. Especially knowledge intensive services firms are deviant. For the connection with firm entry rates, it appears that high shares of firms in the arts and knowledge intensive business services are significantly connected with regional firm entry rates, while media and entertainment and creative business services remain insignificant. Implications for practitioners and future research are discussed. �

Three phases of Dutch economic growth and technological change, 1815-1997

In this paper we analyze the dynamics of Dutch economic growth for the period 1815-1997. By applying a simple econometric technique, important braking points in the timeseries are traced. It seems that three phases of growth can be discerned and that these phases are characterized by different types of technology (steam, electricity as well as information and communication technology). The Dutch economy has not generated an overall productivity improvement from the first and third technological phase, but has been successful in exploiting the technological opportunities of the second phase.
