Motivated by the disintegration of supply networks observed in the automotive, textile and electronics industry, we discuss the impact of such phenomena on the network players. We hypothesize that the state of disintegration is not sustainable and will be followed by an eventual reintegration. We present evidence from a field study that was conducted to understand the impact of disintegration o...

In this paper, we embed the microeconomic decisions associated with investment under uncertainty, capacity utilization, and machine replacement in a general equilibrium model based on putty-clay technology. We show that the combination of log-normally distributed idiosyncratic productivity uncertainty and Leontief utilization choice yields an aggregate production function that is easily charact...

Abstract Stocks' closing price levels can provide hints about investors' aggregate demands and aggregate supplies in the stock trading markets. If the level of a stock's closing price is higher than its previous closing price, it indicates that the aggregate demand is stronger than the aggregate supply in this trading day.

In the aggregate freight demand modeling literature, temporal assignment (annual to daily flows) is often oversimplified or neglected altogether. Unlike passenger flows, freight flows over the course of a year are not uniform and can vary significantly as the result of trade-offs between inventory and transportation cost management. We introduce the first temporal assignment model that explicit...

Nevertheless, it enables us to analyse the broad trends that have occurred over the past twenty years on both the demand and supply sides of the labour market. In the next section we examine these trends at an aggregate level. The aggregate unemployment rate has risen as a result of a ...
