In solving certain optimization problems, the corresponding Lagrangian dual problem is often solved simply because in these problems the dual problem is easier to solve than the original primal problem. Another reason for their solution is the implication of the weak duality theorem which...

This paper examines the empirical evidence of the liquidity effect in Canada. In the presence of the liquidity effect, the initial impact of an unanticipated expansionary monetary policy is to lower nominal and real interest rates for a short period of time. Eventually, however, the anticipated...

Every state has to balance its revenue and expenditure in order to meet its assigned budgetary requirements. Pension is also a part of the states’ expenditure, and since there was the concept of defined benefit scheme till the year 2004, the entire liability of pension expenditure was solely...

In this paper, the authors use the vector autoregression method to examine the effects of monetary policy in Canada including the empirical evidence of the liquidity effect in particular. They use the excess cash reserves of the chartered banks and the surprise component of excess cash reserves...

ILO pub-WEP pub. Working paper on the energy and economic implications of the choice of technology for agricultural technology, based on an analysis of rice production - develops a mathematical model with which comparisons of crop yields, power consumption, labour demand, fixed capital costs,...

A study has been conducted to investigate current practices on decision-making under risk and uncertainty for infrastructure project investments. It was found that many European countries including Australia, the U.K., France, and Germany use scenarios for the investigation of the effects of...

An attempt has been made to estimate the potential of using biogas plants, solar cookers and improved cookstoves for domestic cooking in India. Based on 1991 statistics on the bovine population and ownership pattern, the potential number of family size biogas plants comes out to be around 38...

Heat transfer in a solar water heater could be enhanced by means of twisted tapes, inserted inside the fluid flow tubes, which induce swirl flow and act as turbulence promoters. Experimental investigations for a solar water heater with twisted tape inserts having twist pitch to tube diameter...

This paper uses commuting times and distance data from the Nationwide Personal Transportation Studies of 1977 to 1983-4 to re-evaluate the spatial mismatch hypothesis. Neither minorities nor low-income workers have longer commutes. In fact, their commuting patterns are very similar to those of...
