Every nation of the world confirms that human-related greenhouse gas emissions are the major driver of the present global climate change. About 20% populations of the world live in China and the emissions of greenhouse gases of it are very high due to the large population, inefficient capital...

This paper discusses the aspects of lease financing in Bangladesh. Bangladesh is a small but densely populated country in the South Asia and the people of it mainly depend on agricultural. Due to globalization and liberalization the country gradually shifting towards industrialization and lease...

This paper discusses mathematical calculations of the greenhouse gas emissions from small industries, which cause global warming in the atmosphere. Global warming is causing an increase in ocean levels, it is estimated that most of the coastal areas of the world will be submerged by 2050,...

The single transferable vote (STV) is a system of preferential voting designed to minimize wasted votes. In STV, a constituency elects two or more representatives per electorate. As a result the constituency is proportionally larger than a single member constituency from each party. Political...

An exact solution of Einstein equation is easier than actual solution. The Schwarzschild metric is established on the basis of Einstein’s exact solution and it is also a static and stationary solution. The Schwarzschild solution expresses the geometry of a spherically symmetric massive...

The purpose of this paper is to study the green marketing which incorporates a broad range of activities such as the product modification, changes to the production process, packaging changes, as well as modifying advertising of the environment friendly commodities. Sustainable forest management...

In today’s changing world the business environment is changing rapidly. The emergence of e-commerce and development of information and technology plays a significant role in the nature of work as well as their attitude towards the organization. We have been experiencing a tremendous growth in...

In this paper an attempt has been taken to describe various types of voting system and manipulation of them. French philosophers Marquis de Condorcet (1743-1794) and Jeans-Charles Borda (1733-1799) introduced modern voting system. Duncan Black first introduced the manipulation of voting in 1958...

This paper discusses both social welfare and social choice using Arrow’s impossibility theorem for multi-profile preference case and two versions of it for single-profile preference case. Between these two versions first one assumes a two-individual society and the second one, which is similar...

Mathematical Economics is closely related with Social Choice Theory. In this paper, an attempt has been made to show this relation by introducing utility functions, preference relations and Arrow’s impossibility theorem with easier mathematical calculations. The paper begins with some...
