Exponential smoothing;Smoothing techniques 2
The document shows quarterly actual and forecasted market share values for a firm using two different weighting factors (w) of 0.3 and 0.5 to calculate the forecast. It includes the actual and forecasted values for each quarter, the difference between actual and forecasted, and the squared differences. It calculates the root mean squared error (RMSE) for each weighting factor by taking the square root of the total squared differences divided by the number of periods. The RMSE is 2.70 for w=0.3 and 2.91 for w=0.5, indicating the forecast with w=0.3 had a lower error.
Time series Analysis
This document defines time series and its components. A time series is a set of observations recorded over successive time intervals. It has four main components: trend, seasonality, cycles, and irregular variations. Trend refers to the overall increasing or decreasing tendency over time. Seasonality refers to predictable changes that occur around the same time each year. Cycles have periods longer than a year. Irregular variations are random fluctuations. The document also discusses methods for analyzing time series components including additive, multiplicative, and mixed models.
Forecasting exponential smoothing
Exponential smoothing uses all past time series values to generate forecasts, with less weight given to older values. It works by calculating a smoothed level (Lt) at each period t as a weighted average of the current value (yt) and the previous smoothed level (Lt-1). The forecast for the next period (Ft+1) is then set equal to the current smoothed level (Lt). Choosing the smoothing constant (α) determines how responsive the smoothed level is to recent changes in the data.
Analysis of Time Series
This document discusses time series analysis. It defines a time series as values of a variable ordered over time. Examples of time series include climate data, financial data, and demographic data. Time series analysis is important for understanding past behavior, predicting the future, evaluating programs, and facilitating comparisons. Components of a time series include trends, cyclic variations, seasonal variations, and irregular variations. Several methods are discussed for measuring and decomposing these components, including moving averages, least squares, and seasonal indices.
time series analysis
This document provides an overview of time series analysis and its key components. It discusses that a time series is a set of data measured at successive times joined together by time order. The main components of a time series are trends, seasonal variations, cyclical variations, and irregular variations. Time series analysis is important for business forecasting, understanding past behavior, and facilitating comparison. There are two main mathematical models used - the additive model which assumes data is the sum of its components, and the multiplicative model which assumes data is the product of its components. Decomposition of a time series involves discovering, measuring, and isolating these different components.

Multi product pricing
Firms often produce multiple related products. When products are substitutes, increasing production of one reduces demand for the other. When complementary, increasing one boosts demand for the other. Profit maximization requires jointly determining prices and output levels. A firm should produce quantities where the marginal revenue from each product equals marginal cost. It prioritizes producing profitable products up to the point where the least profitable product's marginal cost equals marginal revenue. Joint products have interconnected production and demand. Firms maximize profits by setting marginal revenue of each joint product equal to their shared marginal cost.
Pricing Strategies;Transfer pricing- managerial economics
This document discusses transfer pricing, which refers to the rules and methods for pricing transactions within divisions of the same company. It provides examples of how the transfer price for an intermediate good is determined between a production and marketing division with no external market, a competitive external market, and an imperfectly competitive external market. In all cases, the transfer price is set to maximize total profits for the company based on the marginal costs and revenues of both divisions.
International price discrimination
This document discusses international price discrimination, also known as dumping. It explains that dumping occurs when a firm charges a lower price abroad than at home for the same good due to higher price elasticity of demand in foreign markets. This allows the firm to earn higher profits than selling at a single price globally. The demand curve is downward sloping in the domestic market where the firm has monopoly power, and perfectly elastic in foreign markets where it faces competition. The firm determines the optimal output level where marginal cost equals aggregate marginal revenue from both markets. It then divides output between markets, charging different prices to extract the maximum profits possible through price discrimination.
Price discrimination with graphical representation
This document discusses different types of price discrimination. It defines price discrimination as charging different prices for the same product when costs are equal. There are three degrees of price discrimination: first, second, and third. First degree involves charging each customer the maximum they are willing to pay. Second degree sets uniform prices in blocks that get lower at higher quantities. Third degree discriminates across different markets that have different price elasticities of demand. To practice discrimination, a firm needs monopoly power and the ability to segment markets.
Cost plus pricing
This document discusses different pricing concepts and methods for determining prices, including cost-oriented, demand-oriented, and competition-oriented pricing. It focuses on cost-oriented pricing, where prices are calculated by estimating costs of production and adding a profit margin. Specific cost-based pricing methods discussed include cost-plus pricing, break-even pricing, target return pricing, and early cash recovery pricing. Cost-plus pricing adds a markup percentage to estimated average costs to determine price. While simple, it ignores demand conditions.
Peak load pricing
Peak load pricing is a strategy where high prices are charged during times of peak demand for goods and services. It is a form of intertemporal price discrimination based on efficiency, where a firm charges more for high usage at busy, high-demand times compared to low demand times. This strategy is commonly used for non-storable goods like electricity, transportation, and communication services that must be produced in real-time to meet fluctuating demand and have higher marginal costs during peak periods due to the limited capacity to increase production.
Penetration priing
Penetration pricing is a strategy used by new entrants to gain market share by initially setting low prices. It aims to quickly switch customers from competitors by creating brand loyalty and generating significant demand. A company can use penetration pricing when there is little product differentiation, demand is price-elastic, and economies of scale can be realized. An example is a company entering the notebook market and selling notebooks below cost at $5.50 to capture market share from competitors selling at $10, utilizing their large production capacity. The strategy allows for rapid adoption but risks customers expecting permanently low prices and a price war damaging profitability long-term.
Pricing problems
This document discusses pricing strategies over the different stages of a product's lifecycle. It identifies the four stages as introduction, growth, maturity, and decline. In the introduction stage, companies must decide between penetration and skimming pricing. In growth, prices can be more aggressive to boost profits. Maturity and decline bring strong competition, calling for price adjustments. The document also discusses factors like market growth rates, costs, mixed strategies, and approaches for pricing in maturity and decline.
Index numbers concepts
The document discusses various types of index numbers used to measure inflation and changes in prices over time. It describes price indexes as single numbers that indicate price changes across goods compared to a base year. Retail price indexes (RPI) and consumer price indexes (CPI) measure average price changes of goods in a typical consumer basket. Chain indexes use successive years as bases to calculate price relatives and chain them together to measure inflation without a fixed base year.
Money and credit
The banking system in India evolved over centuries, with references to moneylending and creditors found as far back as 400 BC. Indigenous bankers operated in India throughout this period, though most did not accept deposits. The foundations of the modern Indian banking system were laid prior to independence, with the establishment of the first joint-stock banks in major cities in the 18th-19th centuries. After independence, the government nationalized major banks to facilitate planned economic development and increase lending in rural areas.

National income measures the total value of goods and services produced within an economy over a period of time without duplication. It is important for economists to measure national income to analyze economic growth, standard of living, and income inequality. National income can be measured using the product method, income method, or expenditure method. Each method involves estimating the total GDP, GNP, or NNP through summing the value of final goods/services, total income, or total expenditures respectively in an economy. There are challenges to accurately measuring national income such as avoiding double counting, accounting for transfer payments, and calculating depreciation. National income statistics are used for economic policy formulation, studying economic structure, and comparing economic welfare across countries.

"Does Foreign Direct Investment Negatively Affect Preservation of Culture in the Global South? Case Studies in Thailand and Cambodia."
Do elements of globalization, such as Foreign Direct Investment (FDI), negatively affect the ability of countries in the Global South to preserve their culture? This research aims to answer this question by employing a cross-sectional comparative case study analysis utilizing methods of difference. Thailand and Cambodia are compared as they are in the same region and have a similar culture. The metric of difference between Thailand and Cambodia is their ability to preserve their culture. This ability is operationalized by their respective attitudes towards FDI; Thailand imposes stringent regulations and limitations on FDI while Cambodia does not hesitate to accept most FDI and imposes fewer limitations. The evidence from this study suggests that FDI from globally influential countries with high gross domestic products (GDPs) (e.g. China, U.S.) challenges the ability of countries with lower GDPs (e.g. Cambodia) to protect their culture. Furthermore, the ability, or lack thereof, of the receiving countries to protect their culture is amplified by the existence and implementation of restrictive FDI policies imposed by their governments.
My study abroad in Bali, Indonesia, inspired this research topic as I noticed how globalization is changing the culture of its people. I learned their language and way of life which helped me understand the beauty and importance of cultural preservation. I believe we could all benefit from learning new perspectives as they could help us ideate solutions to contemporary issues and empathize with others.
