This paper gives a model of collusion formation and a method of measuring the degree of it among the traders/bidders in the agricultural commodity markets in India. The important assumption is that the bidding is repetitive with a set of common bidders. The theory has been derived based on the behavior of the wholesale market of agricultural commodities in India. The paper is based on full information in the collusion formation. The paper first derives the theoretical structure of the bidders' behavior and thereafter derives a measure of collusion formation with the help of real-life data.

The paper used the standard theory of optimization and the theory of auction and probability statistics.

This is a complete information model of cartel formation. The bidding is repetitive and continues forever in discrete time. Hence bidders behavior is observable. Using the proposed method, if the APMC measures for each market and publishes on a periodic basis, say weekly basis, then it will be easier to break the collusion in the market where relative collision is present. For example, if a farmer has three options to sell in three different markets, then the published data would help them to select the market where the degree of collusion is relatively lower. Moreover, the undesirable loss can be avoided based on the right choice of market. As a result, transaction costs will be optima.

The fast depletion of natural resources that has resulted in the scarcity of resources and degradation of environment and the subsequent conflict over resources within and among the states have given rise to a growing concern for environmental security all over the world. It may be pointed out here that since the beginning of human civilization, humans have been relying on the environment for their needs and demands. Therefore, the concern of human beings to the environment has been always and obvious. But now with the depletion of natural resources, the concern for environmental security is being advocated. The purpose of this paper is to analyze environmental issues in the context of South Asia. It may also be added here that in a situation as stated above, any stress on the environment can cause conflicts involving violence within the state as well as between the nation states. Moreover, this paper will look into other issues related to the environment degradation in India and Bangladesh.

The first approach confines environment to the nature and the problems and constraints related to it. It can be termed as ecological approach. This approach is too narrow in its scope, as nature alone is not responsible for many types of hazards. How it is being exploited and protected is equally important. The other approach has been termed as the maximize approach and it includes both the ecology and its human domains. This approach takes into consideration the interaction between the two. It believes that the excessive dependence of human beings affects the environment. Also, the depletion and degradation of the environment affect human beings. The environmental security has to include both the domains and understand their inter-linkages. In fact, the uses of environment and its proper maintenance are related to the human domains.

The environment-related problems and their implications are more similar in both countries. It is true that there is a growing awareness on environmental issues in almost all the countries in the last few years and the individual countries have persuaded environment-friendly policies in certain sectors. Apart from this regional level, a common approach to securing the environment may involve the following aspects: sharing of knowledge and expertise regarding population control measures, policies and programs; cooperation for development and poverty eradication; regularization of inter-state migrations, evolving a regional framework for controlling, repatriation and rehabilitation of refugees; establishment of a system of disaster management and disaster preparedness at the regional level; exchange of knowledge and research works on seismic tremors, earthquakes, and landslides, their causes and possibilities; evolving common flood control measures and development of a regional flood warning system; common measures can be taken up for increased agriculture productivity, treatment of salinity, development of cyclone warning system, reforestation, development of water resources, air pollution control system, etc.

This research will not only be useful for India and Bangladesh but also for other South Asian countries and developing countries as well.
