The role of money and monetary policy of the central bank in pursuing macroeconomic stability has significantly changed over the period since the end of World War II. Globalization, liberalization, integration, and transition processes generally shaped the crucial milestones of the macroeconomic development and substantial features of economic policy and its framework in Europe. Policy-driven changes together with variety of exogenous shocks significantly affected the key features of macroeconomic environment on the European continent that fashioned the framework and design of monetary policies.

This chapter examines the key basis of the central bank’s monetary policy on its way to pursue and preserve the internal and external stability of the purchasing power of money. Substantial elements of the monetary policy like objectives and strategies are not only generally introduced but also critically discussed according to their accuracy, suitability, and reliability in the changing macroeconomic conditions. Brief overview of the Eurozone common monetary policy milestones and the past Eastern bloc countries’ experience with a variety of exchange rate regimes provides interesting empirical evidence on origins and implications of vital changes in the monetary policy conduction in Europe and the Eurozone.

Purpose: This chapter looks specifically at the sources of economic policy uncertainty in Nigeria, and discusses their impact on the Nigerian economy while drawing implications for Africa. It identifies factors that transmit uncertainty in economic policy in Nigeria and draw implications for other African countries.

Methodology: This chapter uses a literature survey methodology to identify the sources of economic policy uncertainty in Nigeria.

Findings: The identified sources of economic policy uncertainty in Nigeria are: the frequent changes in central bank policy, unexpected changes in government policy, political interference, unexpected fall in global oil price, recession, and unethical practices.

Implications: The implication of the study is that rising economic policy uncertainty in Nigeria can have a significant effect on the Nigerian economy and for connected African countries.

Originality: Previous studies have not examined the sources of economic policy uncertainty in Nigeria.

The influence of the household balance sheet, the supply of credit, and uncertainty on consumer spending during the early years of the Great Depression in the USA are assessed within a unified life-cycle consumption function framework. Income uncertainty played the dominant role in the spending declines of 1930 and 1932. The depletion of households' financial assets contributed modestly to the consumption falls in 1931–1932. Indebtedness, the severe penalties surrounding installment debt default, and the supply of credit had little effect on the consumer spending slump.

We document how inflation expectations evolved in the United States during the fall of 1933 using narrative evidence from historical news accounts and the forecasts of contemporary business analysts. We find that inflation expectations, after rising substantially during the spring of 1933, moderated in the fall in response to mixed messages from the Roosevelt Administration. The narrative accounts and our econometric model connect the dramatic swings in output growth in 1933 – the rapid recovery in the spring and the setback in the fall – to these sudden movements in inflation expectations.

Salop and Stiglitz analyzed an equilibrium search model under a Stackelberg assumption that consumers could react to changes in the distribution of prices charged by firms even though they did not know which particular firms were charging the lowest price. In this chapter we assume that firms and consumers move simultaneously so that consumers cannot react to changes in the price distribution. We also assume that a firm cannot limit sales if demand exceeds its desired supply at the price it sets. In contrast to Salop and Stiglitz, a single-price equilibrium at the monopoly price always exists. For most distributions of consumer search costs, a range of two-price equilibria will also exist. In the two-price equilibria, the high price is always the monopoly price while the low price varies in a range above the minimum of average total cost.

We find equilibrium price distributions in a search model with asymmetric duopolists whose marginal costs differ. There are informed consumers who know both prices and buy at the lower one and uninformed consumers who, not knowing prices, choose a store arbitrarily. With asymmetries, pure strategy equilibrium can exist and, even when not, atoms can exist in the firms' price distributions. One surprising result is that increasing the low cost store's marginal cost can lower average prices and raise the expected utilities of both types of consumers. When the low cost firm is foreign, this could justify imposing a tariff.

Propensity to dollarize in Latin America in the demand-side of some economies of the region has a strong political risk component which, in the past, was mainly carried out by inflationary pressures. Coping with risk meant holding FCDs. A recursive multilevel model is developed and empirically tested with Colombia’s data to stress a country-specific tendency to dollarize due to political risk. The chapter’s conclusions suggest that consideration of issues, policies and implications inherent to the decision to dollarize cannot ignore that, the solution to any government-enforced dilemma in the supply-side of these economies, is also politically motivated. Results of a survey are also provided.
