Inflation, government transfers, and optimal central bank independence

The problem of monetary policy delegation is formulated as a two-stage non-cooperative game between the government and the central bank. The solution to this policy game determines the optimal combination of central bank conservatism and independence. The results show that the optimal institutional design always requires some degree of central bank independence and that there is substitutability between central bank independence and conservatism. The results also show that partial central bank independence can be optimal and that there are circumstances under which it is optimal for the government to appoint a liberal central banker.     

The optimal choice of central bank independence and conservatism under uncertainty

This paper examines the optimal monetary delegation arrangement of central bank independence and conservatism in the presence of uncertainty about the central bank’s output objective. We show that full independence is no longer optimal with uncertain central bank preferences, and that optimal delegation involves the choice of both independence and conservatism. Further, we find that the usual trade-off between independence and conservatism no longer necessarily holds. Consequently, high central bank independence may also require a high level of conservatism.     

Independence Before Conservatism: Transparency, Politics and Central Bank Design

Abstract. The problem of monetary policy delegation is formulated as a two‐stage game between the government and the central bank. In the first stage the government chooses the institutional design of the central bank. Monetary and fiscal policy are implemented in the second stage. When fiscal policy is taken into account, there is a continuum of combinations of central bank independence and conservatism that produce optimal outcomes. This indeterminacy is resolved by appealing to practical considerations. In particular, it is argued that full central bank independence facilitates the greatest degree of policy transparency and political coherence.     

Do central bank law reforms affect the term in office of central bank governors?

In this paper we confirm the hypothesis that central bank independence reforms reduce the likelihood that a central bank governor will be replaced. However, the strength of this effect depends on the rule of law and the degree of political polarization.

Central bank independence,fiscal deficits and currency union: Lessons from Africa

Can central bank independence (CBI) help to reduce fiscal balances? In this paper, we answer this question using novel measures of CBI based on the turnover rate of central bank governors (TOR) and the Garriga measure of legal independence for 30 African countries for the period 1990–2017. Our novel measures of CBI capture the degree of alliance between the fiscal authority and the monetary authority which can potentially lead to debt monetization and higher fiscal balances. Thus, we classify central bank governor changes into ally changes or non-ally changes; in addition to that, we decompose our full sample into CFA zone countries and non-CFA zone countries to capture the effect of currency union membership. Our results show that for CFA zone countries, central bank autonomy, when proxied by the turnover rate of central bank governors, is associated with a decrease in fiscal balances and replacing a central banker with a non-ally, is negatively and significantly associated with fiscal balances.     

More effective than we thought: Central bank independence and inflation in developing countries

This study examines the effect of legal central bank independence on inflation in developing countries. In spite of the policy consensus suggesting that central bank independence is an effective tool to control inflation, the evidence is still limited, particularly for developing countries. Using a novel dataset, we analyze the effect of central bank independence on inflation for a sample of 118 developing countries between 1980 and 2013. We find that higher central bank independence is associated with lower inflation rates. This effect on inflation is stronger the more democratic a country is, but it is also present in non-democratic countries. Our results are robust to different specifications and methodologies. Furthermore, we find that all dimensions included in the measurement of central bank independence (objectives, personnel, policy, and financial independence) contribute to curb inflation. Our results shed light on which types of reforms may be more effective at fighting inflation in developing countries.     

Why are price stability and statutory independence of central banks negatively correlated? The role of culture

This paper investigates whether in OECD countries the negative relation between central bank independence and inflation is related to culture, in the sense of common values and norms. It appears that inflation is lower in countries where people dislike uncertainty. Countries, where inhabitants perceive that there should be an order of inequality and a centralisation of authority, are characterised by a dependent central bank and, to a lesser extent by relatively high inflation rates. Hence, the national attitude towards inequality among people appears to be a third factor explaining the negative correlation between inflation and the degree of central bank independence.     

Central Bank Independence and the Cost of Disinflation: Why the Wage Contracts Length Matters?

Recent empirical contributions demonstrate that countries with less independent central banks enjoy lower output losses during disinflationary cycles. To explain these somewhat surprising empirical findings, some authors suggest that independent central banks probably face a flatter short-run Phillips curve. In this paper, we provide both theoretical and empirical arguments to rationalize this intuition. We demonstrate that, since central bank independence reduces the mean inflation rate and its variance, wage setters opt for a lower degree of nominal wage indexation leading to more wage and price inertia and, thus, to a flatter short-run Phillips curve. Consequently, this paper put forward a channel of positive influence of central bank independence on the sacrifice ratio through its impact on nominal wage indexation. Empirical tests, performed using a sample of 19 OECD countries during the 1960–1990 period, show that these theoretical results hold also empirically.     

Is inflation targeting feasible in Poland?

In this paper we analyze whether inflation targeting is feasible in Poland. There are at least three prerequisites for successful inflation targeting: 1) central bank independence, 2) a high degree of central bank accountability, transparency, and communication to the public, and 3) a predictable and stable relationship between inflation and the instruments of monetary policy. While the first two prerequisites are relatively easy to analyze, the third criterion requires formal statistical analysis, which we undertake in this paper. The first two prerequisites for targeting are found to be met in Poland, and the empirical analysis shows some evidence of significant relationships between inflation and monetary instruments in Poland. Hence inflation targeting appears feasible in Poland.     

Does greater central bank independence really lead to lower inflation? Evidence from panel data

It has long been held that central bank independence (CBI) from political control is a necessary requirement to curb inflation. In recent times, however, this long held belief has been challenged. Using a recently compiled panel data set on central bank independence measures, the proposition that greater CBI leads to lower inflation is tested, using latent variable analysis. The use of this alternative econometric technique, along with two additional indicators that capture more appropriately the degree of de facto independence, leads to empirical results that are highly supportive of the negative relationship between CBI and inflation, thereby restoring faith in the conventionally held wisdom, that greater CBI is needed to lower inflation.     

Strategic Interactions of Monetary Policymakers and Wage/Price Bargainers: A Review with Implications for the European Common-Currency Area

This paper reviews recent work on macroeconomic management with varying organization of wage/price bargaining and degrees of credible monetary conservatism. The emerging literature synthesizes and extends theory and empirics on central bank independence (CBI) and coordinated wage/price bargaining (CWB), arguing that the degrees of CBI and CWB interact with each other and with other political-economic conditions (sectoral composition, international exposure, etc.) to structure the incentives facing actors involved in monetary policy and wage/price bargaining. The core implication, theoretically surprising but empirically supported, is that even perfectly credible monetary conservatism has long-run, equilibrium, on-average real effects, even with fully rational expectations, and that these effects depend on the organization of wage/price bargaining. Conversely, wage/price-bargaining structure has real effects that depend on the degree of credible conservatism reflected in monetary-policy rules. Each also has interactive nominal effects though this is less surprising. Some disagreement remains over the precise nature of these interactive effects, but all emerging theory and evidence agree that a common, credibly conservative European monetary policy has nominal and real effects that depend on the Europe-wide institutional-structural organization of wage/price bargaining. Indeed, the one specific piece of theoretical and empirical agreement suggests that, for many member countries, the nominal gains from monetary-policy delegation to a credibly conservative European Central Bank will worsen these bargaining-policy interactions.     

Central bank independence and stock market returns in emerging economies

We investigate the effect of central bank independence on stock market returns in emerging economies. We find evidence for a positive overall effect, but economic independence of the central bank appears to be more relevant than political independence.     

中央银行的宏观监管职能:经济效果与影响因素分析

文章以跨国数据为基础,对中央银行是否应分离银行监管职能这一问题进行了系统的实证分析。结果表明,在中央银行未分离或未完全分离银行监管职能的国家,其金融稳定性通常更高,经济增速更快,而且未出现明显的"通货膨胀倾向"。这意味着金融监管的独立性并不是简单地将监管职能从中央银行分离的问题,中央银行的独立性也并不必然排斥其继续实施金融监管职能。通过将货币政策和金融监管的兼容性置于政治经济学框架下加以解读,文章发现真正影响金融监管实际独立性的并非监管主体的设置问题,而是更广泛地依赖于不同的政治制度条件。上述结论表明,如何在既定的政治制度和政策框架下切实加强货币政策和金融监管的协调与配合才是问题的核心和关键。     

Central bank independence,inflation and political instability in developing countries

We test whether political instability affects central bank independence in developing countries. Both a legal measure and the turnover tate of central bank governors are used as proxies for central bank independence and the frequency of government transfers is used to proxy political instability. Only the number of coups affects the turnover rate of central bank governors. We also find that both the turnover rate of central bank governors and political instability affect the rate of inflation.     

The influence of government ideology on monetary policy: New cross‐country evidence based on dynamic heterogeneous panels

Using data of 23 OECD countries over the 1980–2005 period, we examine whether government ideology affects monetary policy, conditional on central bank independence. Unlike previous studies in this line of literature, we estimate central bank behavior using forward‐looking and real‐time data in Taylor rule models and use estimators that allow for heterogeneity across countries. Our models with heterogeneous slope coefficients for the full sample do not suggest partisan effects. We also do not find evidence that central bank behavior is conditioned by the interaction of the ideology of the incumbent government and the electoral calendar.     

Central Bankers and Central Bank Independence

This paper uses results of a questionnaire survey to look at how central bankers inthe Czech Republic, Hungary, Poland and Slovakia view various criteria of centralbank independence and compares their responses with central bankers in industrialcountries. Central bankers from both groups agree very strongly on the importanceof two pillars of central bank independence: goal independence and freedom toimplement these goals, together with a system of how credit is granted by a centralbank to a government that gives the central bank powers to determine terms andlimits the extent of such credit. Based on the responses, the paper also identifiessome weaknesses of the most frequently used indices of central bank independenceand makes recommendations on how to improve them.     

Central Bank Independence in Transition Economies

The paper discusses recent changes in central bank laws and the relationship between inflation and central bank independence in transition economies. Two indices of legal independence are constructed, covering political and economic aspects of independence. Most of the countries experienced high-inflation episodes in the recent past and changes introduced to the laws after, or simultaneously, with stabilization programmes strengthened the position of the central banks. In further analysis, an inverse relationship emerges between inflation and indices of central bank independence. However, the robust relationship is present only at a high level of economic liberalization. This conclusion is supported by results from regressions on time-aggregated and panel data, even after controlling for the government fiscal position and the absence/presence of an IMF stabilization package.     

MONETARY POLICY WITH A WIDER INFORMATION SET: A BAYESIAN MODEL AVERAGING APPROACH

Monetary policy has been usually analyzed in the context of small macroeconomic models where central banks are allowed to exploit a limited amount of information. Under these frameworks, researchers typically derive the optimality of aggressive monetary rules, contrasting with the observed policy conservatism and interest rate smoothing. This paper allows the central bank to exploit a wider information set, while taking into account the associated model uncertainty, by employing Bayesian model averaging with Markov chain model composition. In this enriched environment, we derive the optimality of smoother and more cautious policy rates, together with clear gains in macroeconomic efficiency.     

Optimal Inflation Contracts and Inflation Targets with Uncertain Central Bank Preferences: Accountability Through Independence?

This paper examines some problems which arise when monetary policy is delegated to an independent central bank and where the central bank's preferences are unknown. Two key conclusions emerge from the paper. First, even with optimal targets or contracts, central bank independence may not always be desirable because central banks may have distorted preferences relative to society. Second, if the delegation solution is preferable, and the independent central bank responds to information about supply shocks, the central bank may be made more accountable by allowing it to set its own inflation targets, i.e. by making it goal-independent
