As we shall see through this volume, Smith's deist views, the sacred rules of nature, the required legislation, and the well-functioning market system converge with what we visualize as an “ideal Islamic system.” Viewed in this light, Smith's thoughts then become systematic and complete in the sense that the Moral Sentiments covers the first part, his Lectures on Jurisprudence covers the second part, and The Wealth of Nations, the third part. This view holds the promise of opening a line of communication between Islamic economics and conventional economics to illuminate how the original visions of Islam and Smith converge. Our position in this regard is of course diametrically opposed to the position held by most that the two disciplines have nothing in common and that the only way to define Islamic economics is to jettison conventional economics: throw the baby out with the bathwater.
Because of market failures and social considerations, truly pure market economies do not exist today. Instead, market or capitalist economies are mixed systems, with the word “mixed” referring to government participation and intervention. Crucially, the questions have become: How much government intervention is acceptable? In what areas?
Mixed Market (Capitalist) Economic System
A number of the shortcomings of a pure market economic system have been noted. We also should add that markets need a “referee” to make sure that important market rules are respected and negative fallouts are contained and limited. Markets are the medium for effective economic performance; they are not an ideology to be placed on a pedestal and untouched, as some would have it.
Private property rights and secure contracts are essential features of a market economy. Property rights give individuals the right to own property and to use that property as they wish. Property rights, in turn, are of no value unless they are secure and legally enforced. Similarly, most economic transactions that are outside the simple retail sphere rely on contracts that must be secure and enforced. In other words, business development needs security and confidence. Without government intervention as the referee, business conditions could become problematic. Moreover, in the absence of business regulations, supervision, and enforcement, businesses could collude and fix prices to the detriment of consumers and society at large. Even without price fixing, monopolies could develop to the detriment of society. At the same time, there are a number of areas where there are natural monopolies, such as defense and some areas of infrastructure. Again, we see a role for government. Most important, even if markets are self-regulating and operate smoothly without government intervention, (namely, how market output is divided among members of society) they may yield results that are socially abhorrent – a few wealthy individuals alongside mass poverty. And most practically, governments needing revenues have to collect taxes to provide even the minimum level of public and social services.
Mixed Socialist Economic System
In large part because of significant income inequality, poverty, human dissatisfaction, and increasing social concerns, some mixed market economies adopted a socialist mantle as an offshoot of Marxism. In Western Europe, socialist parties emerged as strong political contenders to nurture key nationalized industries and expand the available welfare programs. Some countries adopted limited industrial plans. Key sectors, such as banking, telecommunications, railroads, energy, healthcare, and education, were nationalized. The provision of social benefits was expanded to include free education and healthcare, extended unemployment benefits, early retirement for those in hardship industries, minimum retirement benefits, and reduced working hours. These programs increased the role and economic contributions of the state while reducing the role of markets. In the 1980s, the United Kingdom reversed a number of earlier socialist decisions, denationalized some industries, and reduced a number of social programs. This reversal of socialist policies and programs spread to a number of other countries in Western Europe. It was adopted by the International Monetary Fund as the recommended policy prescription and was even forced on some countries during the financial crisis of 2007–2008, in part because of significant public debt and the belief that societies could no longer afford what became considered to be social programs that were too generous.
Command (Planned) Economic System
A command or planned economic system is the polar opposite of a market-based economy. In a command economy, a central public authority makes decisions on the specific goods to be produced, decisions that would be made by individual producers and consumers in a market system. Moreover, in a command economic system, there are no private property rights. Property and resources are collectively owned by groups or by the state. The state or planning organization determines the output of each final good and service sector and those of intermediate goods and services. It decides on wages to be paid and on all remuneration of incomes. From these wage and income figures, consumption and savings are determined. In order to have useful consumption (demand) figures, the planning directives literally go down to the kind and even sizes of shoes to be produced. The output of shoes is so specified (what to be produced), and the inputs have to be dictated (how the goods are produced and the required materials), and so on down the line. In a planned economy, the authorities use an input-output model to derive the
