  1. When and for whom would e-waste be a treasure trove? Insights from a network equilibrium model of e-waste flows

    Wakolbinger, Tina; Toyasaki, Fuminori; Nowak, Thomas; Nagurney, Anna
    Electrical and electronic equipment waste (e-waste) is growing fast. Due to its potential economic value as well as its possible negative impacts on the environment, tracing e-waste flow is a major concern for stakeholders of e-waste management. Especially, whether or not adequate amounts of electrical and electronic equipment waste (WEEE) flow into the designed recycling systems is a fundamental issue for sustainable operations. In this paper, we analyze how technical, market, and legislative factors influence the total amount of e-waste that is collected, recycled, exported and (legally and illegally) disposed off. We formulate the e-waste network flow model as a...

  2. A two-period model with portfolio choice: Understanding results from different solution methods

    Rabitsch, Katrin; Stepanchuk, Serhiy
    Using a stylized two-period model we compare portfolio solutions from two local solution approaches - the approach of Judd and Guu (2001) and the approach of Devereux and Sutherland (2010, 2011) - with the true nonlinear portfolio solution. (authors' abstract)

  3. Summarizing Data using Partially Ordered Set Theory: An Application to Fiscal Frameworks in 97 Countries

    Bachtrögler, Julia; Badinger, Harald; Fichet de Clairfontaine, Aurélien; Reuter, Wolf Heinrich
    The widespread use of composite indices has often been motivated by their practicality to quantify qualitative data in an easy and intuitive way. At the same time, this approach has been challenged due to the subjective and partly ad hoc nature of computation, aggregation and weighting techniques as well as the handling of missing data. Partially ordered set (POSET) theory offers an alternative approach for summarizing qualitative data in terms of quantitative indices, which relies on a computation scheme that fully exploits the available information and does not require the subjective assignment of weights. The present paper makes the case...

  4. House Prices, Capital Inflows and Macroprudential Policy

    Mendicino, Caterina; Punzi, Maria Teresa
    This paper evaluates the monetary and macroprudential policies that mitigate the procyclicality arising from the interlinkages between current account deficits and financial vulnerabilities. We develop a two-country dynamic stochastic general equilibrium (DSGE) model with heterogeneous households and collateralised debt. The model predicts that external shocks are important in driving current account deficits that are coupled with run-ups in house prices and household debt. In this context, optimal policy features an interest-rate response to credit and a LTV ratio that countercyclically responds to house price dynamics. By allowing an interest-rate response to changes in financial variables, the monetary policy authority improves social welfare,...

  5. Firm growth and productivity in Belarus: New empirical evidence from the machine building industry

    Crespo Cuaresma, Jesus; Oberhofer, Harald; Vincelette, Gallina A.
    Using a unique dataset comprising information for (up to) 153 firms in the machine building sector in Belarus, we investigate the determinants of firm growth for an economy where state ownership of enterprises is widespread. We use panel data models based on generalizations of Gibrat's law, total factor productivity estimates and matching methods to assess the differences in firm growth between private and state-contolled firms. Our results indicate that labor hoarding and soft budget constraints play a particularly important role in explaining differences in performance between these two groups of firms.
