For a topical guide to this subject, see Outline of economics. Economics is the social science that studies the behavior of individuals, households, and organizations (called economic actors, players, or agents), when they manage or use scarce resources, which have alternative uses, to achieve desired ends. Agents are assumed to act rationally, have multiple desirable ends in sight, limited resources to obtain these ends, a set of stable preferences, a definite overall guiding objective, and the capability of making a choice. The traditional concern of economics is to gain an understanding of the processes that govern the production, distribution and consumption of goods and services in an exchange economy.[3] An agent may have purposes or ends, such as reducing or protecting individuals from crime, on which he or she wants to spend resources. Definitions There are a variety of modern definitions of economics. J. Economics is a study of man in the ordinary business of life. Microeconomics Related:  The problems with philosophy

Linguistics In the early 20th century Ferdinand de Saussure distinguished between the notions of langue and parole in his formulation of structural linguistics. According to him, parole is the specific utterance of speech, whereas langue refers to an abstract phenomenon that theoretically defines the principles and system of rules that govern a language.[9] This distinction resembles the one made by Noam Chomsky between competence and performance, where competence is individual's ideal knowledge of a language, while performance is the specific way in which it is used.[10] In classical Indian philosophy of language, the Sanskrit philosophers like Patanjali and Katyayana had distinguished between sphota (light) and dhvani (sound). In the late 20th century, French philosopher Jacques Derrida distinguished between the notions of speech and writing.[11] Nomenclature[edit] Variation and Universality[edit] Lexicon[edit] The lexicon is a catalogue of words and terms that are stored in a speaker's mind.

Top Railway Projects that Beat the Slowdown and Kick-Start India’s 2014-2020 Economy | RailNews The ongoing Railway projects that beat the slowdown blues and earn brownie points for the new government, whatever be the political coalition that may come into power at the Centre after May 16, are the top-most Railway infrastructure projects that kick-starts a sluggish economy between 2014-2020. These low-hanging fruits of labour of the two-term UPA government – the Eastern and Western Dedicated Freight Corridor (DFC) projects, the first phase of the Delhi-Mumbai Industrial Corridor (DMIC), Metro Rail Projects in nine cities, Airport modernisation projects in six cities, including Chennai and Kolkata, and power projects that have signed fuel-supply agreements (FSAs) etc are there for the new dispensation to pluck. Here’s a quick status check of these projects, which could help the economy beat the slowdown blues and earn brownie points for the new government. 1. Contracts for another 1,100 km, worth over Rs 7,000 crore (Rs 70 billion), are expected to be awarded in 2014. Delhi Metro: 2.

Utility Economic definitions[edit] In economics, utility is a representation of preferences over some set of goods and services. Preferences have a (continuous) utility representation so long as they are transitive, complete, and continuous. Utility is usually applied by economists in such constructs as the indifference curve, which plot the combination of commodities that an individual or a society would accept to maintain a given level of satisfaction. In finance, utility is applied to generate an individual's price for an asset called the indifference price. Quantifying utility[edit] It was recognized that utility could not be measured or observed directly, so instead economists devised a way to infer underlying relative utilities from observed choice. Utility is taken to be correlative to Desire or Want. Cardinal and ordinal utility[edit] Economists distinguish between cardinal utility and ordinal utility. Utility functions of both sorts assign a ranking to members of a choice set. implies .

Microeconomics This is in contrast to macroeconomics, which involves the "sum total of economic activity, dealing with the issues of growth, inflation, and unemployment."[2] Microeconomics also deals with the effects of national economic policies (such as changing taxation levels) on the aforementioned aspects of the economy.[4] Particularly in the wake of the Lucas critique, much of modern macroeconomic theory has been built upon 'microfoundations'—i.e. based upon basic assumptions about micro-level behavior. Assumptions and definitions[edit] Microeconomic theory progresses by defining a competitive budget set which is a subset of the consumption set. The utility maximization problem is the heart of consumer theory. The utility maximization problem is a simple constrained optimization problem in which an individual seeks to maximize utility subject to a budget constraint. The theory of supply and demand usually assumes that markets are perfectly competitive. Microeconomic topics[edit] Monopoly[edit]

Psychology Psychology is an academic and applied discipline that involves the scientific study of mental functions and behaviors.[1][2] Psychology has the immediate goal of understanding individuals and groups by both establishing general principles and researching specific cases,[3][4] and by many accounts it ultimately aims to benefit society.[5][6] In this field, a professional practitioner or researcher is called a psychologist and can be classified as a social, behavioral, or cognitive scientist. Psychologists attempt to understand the role of mental functions in individual and social behavior, while also exploring the physiological and biological processes that underlie cognitive functions and behaviors. While psychological knowledge is often applied to the assessment and treatment of mental health problems, it is also directed towards understanding and solving problems in many different spheres of human activity.

It has its share of joys and sorrows and yet has marched proudly with the times and has come up a winner in the modern times. Indian history is made up of many cultures of the rulers who invaded India and expanded their empire here. Timeline Ancient India The Indian subcontinent in the ancient times comprised of Pakistan, Bangladesh, Nepal, Tibet and Myanmar. The beginning of the Indus valley civilization can be dated back to 3000BC. Timeline Medieval India 1290 AD, Jalal ud-din Firuz establishes his sultanate at Delhi and here begins the rule of the Mughul Empire in India. Timeline modern India In 1751 AD, Britain becomes the most powerful colonial power in India and defeats Siraj-ud-daulah and seizes power of the northern parts of India. By then the freedom struggle was spread all over the country and people were now against the British rule.

Consequentialism Consequentialism is usually distinguished from deontological ethics (or deontology), in that deontology derives the rightness or wrongness of one's conduct from the character of the behaviour itself rather than the outcomes of the conduct. It is also distinguished from virtue ethics, which focuses on the character of the agent rather than on the nature or consequences of the act (or omission) itself, and pragmatic ethics which treats morality like science: advancing socially over the course of many lifetimes, such that any moral criterion is subject to revision. Consequentialist theories differ in how they define moral goods. Some argue that consequentialist and deontological theories are not necessarily mutually exclusive. Consequentialist philosophies[edit] State consequentialism[edit] Mozi supported a communitarian form of consequentialism, rather than individual pleasure or pain.[4] Utilitarianism[edit] Ethical egoism[edit] Ethical altruism[edit] Rule consequentialism[edit]

Supply and demand The price P of a product is determined by a balance between production at each price (supply S) and the desires of those with purchasing power at each price (demand D). The diagram shows a positive shift in demand from D1 to D2, resulting in an increase in price (P) and quantity sold (Q) of the product. If demand increases (demand curve shifts to the right) and supply remains unchanged, a shortage occurs, leading to a higher equilibrium price.If demand decreases (demand curve shifts to the left) and supply remains unchanged, a surplus occurs, leading to a lower equilibrium price.If demand remains unchanged and supply increases (supply curve shifts to the right), a surplus occurs, leading to a lower equilibrium price.If demand remains unchanged and supply decreases (supply curve shifts to the left), a shortage occurs, leading to a higher equilibrium price.

Behavioral economics There are three prevalent themes in behavioral finances:[3] Issues in behavioral economics[edit] Behavioral finance[edit] The central issue in behavioral finance is explaining why market participants make systematic errors contrary to assumption of rational market participants.[1] Such errors affect prices and returns, creating market inefficiencies. Behavioral finance highlights inefficiencies such as under- or over-reactions to information as causes of market trends (and in extreme cases of bubbles and crashes). Other key observations include the asymmetry between decisions to acquire or keep resources, known as the "bird in the bush" paradox, and loss aversion, the unwillingness to let go of a valued possession. Quantitative behavioral finance[edit] Quantitative behavioral finance uses mathematical and statistical methodology to understand behavioral biases.

Bilateral and regional co-operation Archives - IAS MAINS Latin America has remained at the periphery of Indian political and economic strategy, having presented no significant challenges, received marginal Indian migration (mainly in the Caribbean/Atlantic), and, depending on the country, having limited or no historic or cultural connections with India. In this century, however, economic exchanges, particularly in the energy sector have been significant. The South American continent, along with Central America and the Caribbean (LAC), and their Exclusive Economic Zones (EEZ) are rich in oil and gas, with probable, and even proven, estimates of reserves rising every year. In Venezuela, whose hydrocarbon reserves, as per latest estimates of the OPEC, at 296.5 billion barrels exceed those of Saudi Arabia, ONGC Videsh Ltd (OVL) signed a joint venture (JV) agreement with Venezuela’s state oil company PdVSA, acquiring a 40 percent share in the San Cristobal oil field. In Trinidad and Tobago (T&T), Gas Authority of India Ltd.

Utilitarianism Utilitarianism is influential in political philosophy. Bentham and Mill believed that a utilitarian government was achievable through democracy. Mill thought that despotism was also justifiable through utilitarianism as a transitional phase towards more democratic forms of governance. As an advocate of liberalism, Mill stressed the relationship between utilitarianism and individualism.[10] Historical background[edit] The importance of happiness as an end for humans has long been recognized. Although utilitarianism is usually thought to start with Jeremy Bentham, there were earlier writers who presented theories that were strikingly similar. Hume says that all determinations of morality, this circumstance of public utility principally important. In the first three editions of the book, Hutcheson included various mathematical algorithms " compute the Morality of any Actions." This pursuit of happiness is given a theological basis:[22] …actions are to be estimated by their tendency.
