Introduction

Macroeconomics is the study of the aggregate economy (Kennedy, 2000). It involves the study of variables which affect the whole economy. These variables include Gross Domestic Product (GDP), growth rate, unemployment, inflation, international trade, business cycle and demographic characteristics. The study of these variables helps in understanding the structure and composition of the whole economy in order to make rational decisions which can help the economy grow during the various business stages. This is done through the use of macroeconomic models in analysing the variables data. Each of the macroeconomic variables is an indicator of the level of an Continue reading...

In a competitive market structure the firms face an elastic demand curve. The monopolist on the other hand faces a demand curve that is somewhat inelastic in nature. So we can see that the elasticity of the demand curve faced by a firm can indicate the type of market the firm operates in. The way the demand for the product is affected by the price of the close substitute also gives us an idea whether the firm has any close competitor or not. The demand function and the elasticities that we have obtained from the regression analysis can provide Continue reading...

EFFECTS OF THE FINANCIAL CRISIS IN 2007-2009

Inflation
Prior to the financial crisis most central banks were required to fully commit to regulate the levels of inflation in the country. According to Mishkin, this process is called flexible inflation targeting. He defines it as a phenomena that “Involves a strong, credible commitment by the central bank to stabilize inflation in the long run, often at an explicit numerical level, but also allows for the central bank to pursue policies to stabilize output around its natural rate level in the short run,” (pg. 14). Banks like Federal Reserve were willing to commit to stabile inflation; however, they Continue reading...

In this study we compare the national emissions content of each country against the global average. This study is subject to the experimental weakness known as aggregation bias, in which the behavior of a group is mistaken for the behavior of each individual within that group. By diversifying the number of economic sectors, we can reduce the effect of this source of aggregation bias. The study found that the Continue reading...

Market structures Description

Monopoly market
This is a type of market that features one, if not all, of the characteristics of a monopoly such as supply constraints, high price levels or excessive entry barriers. Due to the type of market, it mainly entail of a single supplying firm and consumers can only buy from this single firm. Without good control or legislation, this firm has the power to increase prices without adversely impacting demand for its services/products. This kind of market is in contrast to a perfectly competitive market.Oligopolistic market
This is a situation where a certain market is controlled by a Continue reading...

Potentiometers are measurement sensors that use a variable resistor to convert a displacement or angle moved through into a voltage/resistance. Potentiometers operate by moving a contact along a variable resistor thus producing a voltage that is proportional to the position. LVDTs (Linear Variable Differential Transformers) comprise a pair of small transformers sharing a magnetic core. Movement of the core causes the output of one transformer to increase and the other to decrease. The current imbalance achieved through this movement is a measure of the core’s position, and optimum linearity occurs at the midpoint where the two transformers are Continue reading...

Many different sellers and buyers exist within a marketplace (Hildebrand, 2009). It implies that there is competition within the market that allows price to fluctuate in response to shifts in supply, as well as demand. Besides, for almost each commodity there exist substitutes, for that reason, whenever a commodity becomes expensive, a purchaser may prefer a cheaper commodity or substitute. In any given marketplace having many sellers as well as purchasers, the supplier and consumer have an equal chance to influence cost or price of transactions (Mankiw & Taylor, 2006). In some sectors, substitutes do not exist and for that Continue reading...

Introduction Data envelopment analysis is a management tool that is increasingly gaining popularity. Data envelopment analysis is used in the evaluation of the efficiency of one or more producers. The definition of a producer is integral to understanding data envelopment analysis. In this respect, producers are the decision making units in a system. Data envelopment analysis is different from a typical statistical approach to analyzing producers (Cooper, 2010). The typical statistical approach entails a central tendency approach where one producer is evaluated against another average producer.

Trade-offs related to inputs in productivity

Productivity is basically the ratio between ‘outputs’ and ‘inputs of a company/firm’s production process. Inputs are converted into outputs during the process. This assignment looks at the trade-offs involving the inputs to productivity.

Input and output factors in productivity calculations

Irrespective of type of industry or scale of operations, input factors include: labor (labor-hours or full-time equivalents); capital goods (machines, equipment) and resources (employees, capital, raw materials and power). Output factors are specified in terms of physical volumes (number of units or tons produced). Inputs and outputs are quantifiable in manufacturing industries, while in service firms difficulties arise in the quantification.

Strategies adopted by firms to increase productivity

Among several strategies to Continue reading...

Introduction

As opposed to continuous time capacitor circuits in analog signal processing, Switched Capacitor (SC) circuits find wide range of applications in discrete time signal processing. These circuits function by charging and discharging capacitors with the help of switches to provide flow of charge in desired direction. SC filters are embedded in integrated circuits due to their inherent temperature and voltage characteristics.

A typical SC circuit is equivalent to a discrete time resistance. Consider a simple example of a SC circuit:

Clock pulses are applied on switches to perform transition between two voltage sources shown in the figure. It is made sure that the clock pulses don’t overlap so that the voltage sources are not short circuited. It Continue reading...

A monopoly is a market structure dominated by only one supplier who supplies a particular product or service which does not have substitutes (Mankiw, pg 330). Monopolies exist because there is restriction of entry into a particular market. The existence of monopoly leads to market failure in an economy. Monopoly power means the ability to set prices by a monopoly firm. Entry into the market is restricted because of the high initial costs involved, complexity of operation, the nature of the product or service, economies of scale and existence of patents, trademarks, copy rights and franchise. The existence of Continue reading...

The different cells of the higher animals create specialized organs, tissues, and systems that have particular functions. For example, the tissue organizations that constitute the respiratory system promote breathing and, hence, allow the exchange of gases. The cardiovascular arrangement employs the blood to transport the gases, as well as other substances in the body. Additionally, the respiratory and cardiovascular systems have a close integration, such that a response to a body change in one system is manifested in the second system. The present study, therefore, investigated the cardiovascular physiology, as well as the integration of the respiratory and the Continue reading...

Introduction

Inflation is the persistent increase in general price level of goods and services over a period of time in a given economy/country (Lindauer, 92). Types of inflation include open inflation, suppressed inflation, galloping inflation, creeping inflation and hyperinflation. Open inflation arise due to rising costs of goods and services. Depressed inflation arises due to price restrictions by the government. Galloping inflation is inflation that rises very fast at a persistent rate. Creeping inflation is inflation that rise slowly but at a steady rate over time. Hyperinflation is caused by increased debt by the government. Inflation is measured using Consumer Continue reading...

Financial markets and institutions

Introduction
In economics, there is one assumption which is considered when analysing markets. This is the assumption that the market has perfect information. However, this is not always the case. Most markets do not have perfect information because it is impossible for consumers to have all information regarding transactions. Since perfect information is not possible in real world, economists have other means of studying markets with imperfect information. This study is known as information asymmetry. Information asymmetry arises when one person has less information concerning a transaction. The study of information asymmetry gives rise to “market for lemons” where Continue reading...

In its early days the main purpose of the Federal Reserve System was to help banks during banking crises and exchange fevers. Initially, the control over the level of bank credit, money supply and rates of interest was not within the purview of the Federal Reserve System. In that time the gold standard was dominated in the United States, and it was assumed that the amount of gold stored in the bowels of the US banking system is the mechanism that regulates the amount of money in circulation and bank credit. The founding fathers of the Federal Reserve System Continue reading...

Interpreting Logistic Regression Output from Excel

Interpreting Logistic Regression Output from Excel

Introduction

When we have a binary output variable Y, and we wish to model the conditional probability of (Y, given X) as a function of X, one approach is to perform logistic regression. Logistic regression introduces the ‘logistic transformation’, log p (x)/(1-p (x). This logistic transformation helps in avoiding results that would not normally make sense. Using this approach, logistic regression helps to determine the probability of a categorical dependent variable based on one or more predictor variables (Carnegie Mellon University, n.d.).
The challenge is to convert this data to a prediction Continue reading...
