How can business leaders make better production and capital investment decisions? How can Wall Street analysts improve their predictions of future stock market values? How can government improve macroeconomic forecasts and policies? In The Power of Profit, Anari and Kolari demonstrate how profit measures can be applied as the basis for these and many other applications of economic, policy, financial, and business analysis. The underlying theme of the book is that profitability is the driving force in free market economies. Firms invest in capital, produce goods and services, and generate sales in an effort to reap profits. Firms that are unprofitable exit the marketplace and are replaced by profitable firms. Despite the crucial importance of profits, however, there is no formal model that directly relates profits to capital formation and output. Previous studies over the past 100 years on profit and the economy are mainly descriptive in nature, without any well-specified model grounded in microeconomic theory. Filling this gap, the authors present a profit system model of the firm grounded in basic accounting relationships in addition to the well-known Cobb-Douglas production function, which can be applied to individual firms, industries, and the business sector as a whole.

Through rigorous data analysis, the authors show how the profit system modelcan be applied to:

The result is a model thatintegrates microeconomic and macroeconomic factors and that can be widely applied in business and economic decisions, policymaking, research, and teaching.

This book proposes a new capital asset pricing model dubbed the ZCAPM that outperforms other popular models in empirical tests using US stock returns. The ZCAPM is derived from Fischer Black’s well-known zero-beta CAPM, itself a more general form of the famous capital asset pricing model (CAPM) by 1990 Nobel Laureate William Sharpe and others. It is widely accepted that the CAPM has failed in its theoretical relation between market beta risk and average stock returns, as numerous studies have shown that it does not work in the real world with empirical stock return data. The upshot of the CAPM’s failure is that many new factors have been proposed by researchers. However, the number of factors proposed by authors has steadily increased into the hundreds over the past three decades.

This new ZCAPM is a path-breaking asset pricing model that is shown to outperform popular models currently in practice in finance across different test assets and time periods.Since asset pricing is central to the field of finance, it can be broadly employed across many areas, including investment analysis, cost of equity analyses, valuation, corporate decision making, pension portfolio management, etc. The ZCAPM represents a revolution in finance that proves the CAPM as conceived by Sharpe and others is alive and well in a new form, and will certainly be of interest to academics, researchers, students, and professionals of finance, investing, and economics. 

Professional investment portfolio management is increasingly utilizing sophisticated statistical and computer techniques to better control risks and improve performance. This book provides new quantitative tools and technology for securities professionals to help boost the performance of their investment portfolios offered to clients. Unlike other books in this area, the authors utilize revolutionary asset pricing methods and models to analyze data for U.S. stocks and show how to apply them to the problem of creating highly diversified portfolios that are efficient in terms of returns per unit risk.
