Capitailist - This system works under private authority and its aim is to earn maximum profit. This is also known as market economy. Prices here are fixed by market forces. Socialist- This system is governed by one central authority and its aim is social welfare.

The purpose of the different economies

As economies allocate goods and services, they emit measurable signals that suggest there is order driving the complexity. For example, the annual output of advanced economies oscillates around an upward trend.

There also seems to be a negative relationship between inflation and the rate of unemployment in the short term. At the other extreme, equity prices seem to be stubbornly unpredictable.

Learning more about the process that generates these stylized facts should help economists and policymakers understand the inner workings of the economy. They may then be able to use this knowledge to nudge the economy toward a more desired outcome for example, avoiding a global financial crisis.

Interpreting reality An economic model is a simplified description of reality, designed to yield hypotheses about economic behavior that can be tested.

An important feature of an economic model is that it is necessarily subjective in design because there are no objective measures of economic outcomes. Different economists will make different judgments about what is needed to explain their interpretations of reality.

There are two broad classes of economic models—theoretical and empirical. They provide qualitative answers to specific questions—such as the implications of asymmetric information when one side to a transaction knows more than the other or how best to handle market failures.

In contrast, empirical models aim to verify the qualitative predictions of theoretical models and convert these predictions to precise, numerical outcomes. The empirical adaptation of the theoretical model would attempt to assign a numerical value to the average amount expenditure increases when income increases.

Economic models generally consist of a set of mathematical equations that describe a theory of economic behavior. The aim of model builders is to include enough equations to provide useful clues about how rational agents behave or how an economy works see box.

Economic models can be quite simple in practice: The less expensive the apples, the more are demanded. Or models can be rather complex: Its basic purpose is to explain and analyze prices and quantities traded in a competitive market.

The market-clearing price is determined by the requirement that supply equal demand at that price. Demand is usually set to decline and supply to increase with price, yielding a system that moves toward the market-clearing price—that is, equilibrium—without intervention.

The supply-demand model can explain changes, for example, in the global equilibrium price of gold.


Did the gold price change because demand changed or because of a one-time increase in supply, such as an exceptional sale of central bank gold stockpiles?

Economic models can also be classified in terms of the regularities they are designed to explain or the questions they seek to answer. Other models are designed to focus on structural issues, such as the impact of trade reforms on long-term production levels, ignoring short-term oscillations.

How economists build empirical models Despite their diversity, empirical economic models have features in common.

Each will allow for inputs, or exogenous variables, which do not need to be explained by the model. These include policy variables, such as government spending and tax rates, or nonpolicy variables, like the weather.Government's Role In The Economy In quite a different area, government supports individuals who cannot adequately care for themselves by making grants to low-income parents with dependent children, by providing medical care for the aged and indigent, and through social insurance programs that assist the unemployed and retirees.

· Agricultural Policies in Emerging Economies. MONITORING AND EVALUATION. Table 1 summarises these different measures in terms of their orientation: whether policies are directly orientated to affect consumers, producers or trade.

Agricultural Policies in Emerging  · The purpose of our study is twofold: First, to estimate the size of the shadow economy of countries all over the world measured as percentage of GDP by using a MIMIC model from to 1 Of course, we are aware that there are overlapping areas,  · A firm expands its scale of production for the purpose of earning larger profits and thereby derives many economies of large scale production which, in turn, help it in lowering the costs of production and increasing its productive The main purpose of the study in hand is together relevant information to compile internship report on PTCL.

To observe, analyze and interpret the relevant data competently and in a useful But if one is interested in comparing the per capita output of different economies it is useful to consider the output by simply using the exchange rates of the different currencies.

This is done for the data that is shown in the map below, the GDP per capita is converted to one single currency: the US-$
