In data envelopment analysis, there are several methods for measuring efficiency change over time, e.g. the window analysis and the Malmquist index. However, they usually neglect carry-over activities between consecutive two terms. These carry-overs play an important role in measuring the...

There are both theoretical and empirical reasons for believing that the pa- rameters of macroeconomic models may vary over time. However, work with time-varying parameter models has largely involved Vector autoregressions (VARs), ignoring cointegration. This is despite the fact that...

This study combines a traditional hypothetical worker approach with the techniques of stochastic forecasting in order to provide a better sense about the suitability of the pension system for formal sector private workers in Thailand. With regard to the proposed defined-contribution pension, we...

Truthful revelation of preferences has emerged as a desideratum in the design of school choice programs. Gale-Shapley's deferred acceptance mechanism is strategy-proof for students but limits their ability to communicate their preference intensities. This results in ex-ante ineciency when ties...

In DEA, there are typically two schemes for measuring efficiency of DMUs; radial and non-radial. Radial models assume proportional change of inputs/outputs and usually remaining slacks are not directly accounted for inefficiency. On the other hand, non-radial models deal with slacks of each...

This paper analyzes the second-best pricing and investment policy for transport networks with a revenue-recycling mechanism in which the toll revenue is used as transport investments or subsidies, as in London’s congestion charging scheme. The results of this paper demonstrate that the way...

By using the Vietnam Household Living Standard Survey in 2004, this paper seeks to quantify the potential role and impacts of a social pension scheme for reducing elderly poverty in Vietnam. We simulate how the poverty rate, poverty gap, and poverty severity of the elderly would have been...

This paper aims to provide a long-term financial vision for the Vietnamese pension scheme using stochastic modeling for key variables under an actuarial framework. In particular, we project the pension fund balances in order to see whether the scheme will be financially sustainable. The median...

The elimination of school fees from public primary education under the Free Primary Education (FPE) Policy in Kenya in 2003 has increased enrollment by 22 percent in the first year alone. Some experts, however, suggest that the FPE has reduced the quality of education in public schools and...
