1 Background Total impact multipliers (TIMs) are factors derived from input–output analysis (IOA) that show the total, economy-wide attribution of impacts from production to one unit of final demand. One example is the attribution of greenhouse gas (GHG) emissions of all industries in an economy to the final demand of a particular product. This metric is called the carbon footprint of the produ...

Investment decisions occupy a central role among the determinants of growth. As empirical studies such as Levine and Renelt (1992) have revealed, fixed investment as a share of gross domestic product is the most robust explanatory variable of a country's growth. DeLong and Summers (1991) also provide evidence emphasizing the correlation of investment in equipment and machinery with growth. New ...

Today, many wireless device providers choose to sell devices bundled with complementary mobile social services, which exhibit strong positive network externality. Taking a reverse engineering approach, this paper aims to quantify the benefits of selling devices and complementary services under the following three strategies: separate pricing, bundled pricing, and hybrid pricing (both the separa...

level: intermediate M ost biopharmaceutical processes involve purifying proteins and peptides from various sources. Typically, purification schemes contain multiple unit operations, including several chromatographic steps to ensure safe removal of critical impurities and contaminants. Each step affects the overall process economy by increasing operational cost and process time and by causing pr...

In this paper we make a critique of the standard stability results already established in a basic two period OLG model. Under an alternative interpretation (competitive financial markets), we are able to select the test equilibrium in the long run, in such a way that the economy can reach the Golden Rule Steady State, even when at this interest rate, all young agents are creditors. We show that...

With the current U.S. economic expansion now in its sixth year, the economy appears to be on a path of stable growth. Such a development would be beneficial because it would foster steady gains in employment, income, and investment, all of which would help boost the overall standard of living. To maintain such a healthy course, most sectors of the economy need to be solid performers. The housin...
