On the System Setup and the Scheduling Problem in a Flexible Manufacturing System (FMS)

In this paper we present a model which unifies several existing models with respect to two phases of the planning process of a Flexible Manufacturing System. These phases are the system setup phase and the scheduling phase and in literature they usually are considered separately. We give a mathematical formulation encompassing both phases. From this formulation several existing approaches can be deduced. We also describe some heuristic methods for our model and present the computational results.     

Equity Issuance and Adverse Selection: A Direct Test Using Conditional Stock Offers

We conduct a unique test of adverse selection in the equity issuance process. While common stock is the dominant means of payment in bank mergers, stock acquisition agreements provide target shareholders with varying degrees of protection against adverse price movements in the bidder's stock between the time of the merger agreement and the time of merger completion. We show that it is the degree of protection against adverse price changes and not the percent of stock offered in a bank merger that explains bidder merger announcement abnormal returns. This result is difficult to explain outside of an adverse selection framework.     

Unemployment and Catching Up: Europe Vis-à-vis the USA

This paper develops a two-region two-sector endogenous growth model with a dual labour market based on efficiency wages. Growth is driven by research done in the (high-tech) tradeables sector. The follower region tends to catch up in terms of labour productivity with the leader region. Differences in unemployment compensation systems can lead to relative convergence, i.e., a steady state with the backward region lagging behind the leader region. The reason for this is that high social welfare compensations generate high unemployment and reduce the amount of labour employed for R&D purposes.

Indonesian Manufacturing Sector Output and Productivity: An Australian Comparative Perspective, 1975–90

This paper provides industry-of-origin comparative estimates of real output and labour productivity in the Indonesian and Australian manufacturing sectors. It makes binary comparisons for the benchmark year 1987, and extrapolates the 1987 benchmark backward and forward using national time series, to derive comparisons for the years 1975–90. Expressed in ‘purchasing power parities’ (PPPs), the gross value of output and value added in Indonesian manufacturing in 1987 was 40% and 34% of the respective Australian levels. In 1987 the Indonesian manufacturing price level was 74% of the Australian level, and Indonesian manufacturing labour productivity was 16% of that in Australia. 1975 to 1990 was a period of catch-up. The Indonesian manufacturing price level declined from 105% to 60% of the Australian level, while labour productivity increased from 12% to 17% of the Australian level. The catch-up was greater from the early 1980s onwards.
