For the many-to-one matching model in which firms have substitutable and quota q−separable preferences over subsets of workers we show that the workers-optimal stable mechanism is group strategy-proof for the workers. Therefore, in centralized markets like entry-level professional labor markets if the proposed matching is the workers-optimal stable matching then, no group of workers can never b...

Optimal tariffs and quotas are comgared for a large country under uncertainty. If the import supply schedule has constant elastjcity and is subject to multiplicative uncertainty and domestic demand is random then the optimal policy is a fixed +.d valorem tariff. If the supply schedule has constant elasticity but this elasticity is random then the optimal tariff is superior to the optimal quota....

We propose a new method for conducting Single Transferable Vote (STV) elections and provide a unified method for describing classic STV procedures (the Gregory Method, the Inclusive Gregory Method and the Weighted Inclusive Gregory Method) as an iterative procedure. We also propose a modification for quota definition that improves the theoretical properties of the procedures. The method is just...

Penrose's limit theorem (PLT, really a conjecture) states that the relative power measure of two voters tends asymptotically to their relative voting weight (number of votes). This property approximately holds in most of real life and in randomly generated WVGs for various measures of voting power. Lindner and Machover prove it for some special cases; amongst others they give a condition for th...

This paper considers the incentive compatibility in many-to-many two-sided matching problems. We first show that the Blocking Lemma holds for many-to-many matchings under the extended max-min preference criterion and quota-saturability condition. This result extends the Blocking Lemma for one-to-one matching and for many-to-one matching to many-to-many matching problem. It is then shown that th...

This paper deals with the development and obstacles of Korean women’s political participation in recent years. Since the year 1948 after the declaration of a modern state, Korea has tried to establish the democracy but still in the field of women’s political participation it meets a lot of problems such as women’s political consciousness, male dominated political culture and institutional const...

The world’s biggest and arguably most aggressive form of employment based affirmative action policy for minorities exists in India. This paper exploits the institutional features of federally mandated employment quota policy to examine its effect on labor market outcomes of two distinct minority groups. My main finding is that a 1-percent increase in employment quota significantly increases the...

Weighted voting games (WVGs) model decision making bodies such as parliaments and councils. In such settings, it is often important to provide a measure of the influence a player has on the vote. Two highly popular such measures are the Shapley– Shubik power index, and the Banzhaf power index. Given a power measure, proportional representation is the property of having players’ voting power pro...
