We document producer price adjustment using a low‐inflation micro price dataset. On average 24% of prices adjust each month, with an average increase/decrease of 6%. Producer prices adjust more frequently than consumer prices, but their size of adjustment is typically smaller. Sectoral heterogeneity in the frequency of price adjustment is strongly related to heterogeneity in the cost structure. Fluctuations in aggregate producer price inflation occur to a large extent through variation in the relative share of upward and downward price adjustment. 相似文献

During the last decade economic literature explored the presence of and reasons for what became known as “the great moderation” in the US and other G7 countries. “The great moderation” describes the decrease in economic volatility experienced in many of the G7 countries. This paper finds that in South Africa volatility is also not constant (it even finds that there are autoregressive conditional heteroskedastic effects present) and that volatility also decreased, particularly since 1994. Following the literature, the paper explores several reasons for this decrease and finds that smaller shocks, better monetary policy and improvements in the financial sector that place less liquidity constraints on individuals and allow them to manage their debt better are some of the main reasons for the reduction in the volatility of the South African economy. The literature on the G7 also suggests that better inventory management contributed to the lower volatility. However, this seems not to be true for South Africa. 相似文献

This study examines the impacts of real exchange rates on the bilateral trade balances of Malaysia with the USA, Japan and Singapore. The results for the long‐run cointegrating vectors show that depreciation or devaluation of real exchange rates will improve bilateral trade balances. In the short run, there is some evidence of the J‐curve phenomenon. Changes in real money supply contribute greatly to changes in real exchange rates. Generally, changes in real exchange rates contribute significantly to changes in bilateral trade balances. Monetary policy can be used to influence bilateral trade balances. 相似文献

In the present paper, we propose an extension of Spengler's (1950) analysis of successive oligopolies, to study the effects of entry in the downstream and upstream markets. Free entry is analyzed using replica economies à la Debreu and Scarf (1963) . We find that free entry may have different effects in the upstream and in the downstream market. Namely, the usual convergence of the price to the corresponding marginal cost only occurs in the downstream market. 相似文献

This paper provides an empirical analysis of the factors accounting for inflation dynamics in Ghana using the bounds test and other econometric approaches. We find that real output, nominal exchange rate, broad money supply, nominal interest rate and fiscal deficit play a dominant role in the inflationary process in Ghana. To the extent that output growth by far has the strongest impact on inflation, targeting supply‐side constraints will help moderate price inflation. The paper concludes that inflation in Ghana is explained by a combination of structural and monetary factors consistent with prior studies. 相似文献

The extant literature is split on the best measure of marginal cost in the New Keynesian Philips Curve, with the output gap and the labor share being the most commonly advocated proxy measures. Which one is the best measure? In this article, I assume that agents update their understanding and expectation period by period, a learning process. In terms of econometrics, I use a recursive Vector Autoregression approach and conduct a forecasting exercise that considers updating of information sets used for formation of expectation. I find that the traditional output gap measure is a more significant variable explaining the dynamics of the U.S. inflation rate, as compared with a measure of the labor income share. Furthermore, the role of the output gap cannot be replaced using lagged values of inflation. Instead, both the output gap and lags of the actual inflation rate are important determinants of inflation. 相似文献

The paper examines a quantity–location duopoly game in a spatial discrimination model in which the delivered goods are assumed to be imperfect substitutes or complements. By extending the range of the unit transportation cost analysed in the existing literature, it is shown that a dispersed equilibrium arises in which the choice of the optimal locations is affected by the degree of product substitutability. The interaction between the latter and the size of the transportation cost is also discussed in order to verify its welfare implications. In particular, it is shown that in this spatial framework imperfect substitutability may increase welfare. 相似文献

The Federal Reserve's Tools for Policy Normalization in a Preferred Habitat Model of Financial Markets 下载免费PDF全文

We develop a model to analyze monetary policy implementation with multiple Federal Reserve liabilities and superabundant reserves. The analysis demonstrates the Federal Reserve's tools including interest on excess reserves (IOER), overnight reverse repurchase agreements (ON RRP), and term deposits should allow the Federal Reserve to raise the short‐term interest rates to any desired level. We find the contribution of each the increase in the IOER and ON RRP offering rates in firming money market rates suggested by the data during the December 2015 policy tightening event is remarkably similar to the effect of each tool implied by the calibrated model. 相似文献

The fixed rate tender is one of the main procedures used by central banks in the implementation of their monetary policies. While academic research has largely dismissed the procedure owing to its tendency to encourage overbidding, central banks such as the ECB and the Bank of England have continued using it. We investigate this apparent conflict by considering an auction-theoretic setting with private information about declining marginal valuations. Since overbidding entails exposure risk, an equilibrium may exist even if bids are costless and the intended volume is pre-announced. In fact, the allotment quota may be strictly below one with certainty. Also with adaptive expectations, overbidding need not escalate. However, the resulting allocation is typically inefficient. Empirical proxies of exposure risk are significant in both euro and sterling operations. Our findings have implications, in particular, for the potential reintroduction of pro rata allotment in the main refinancing operations of the Eurosystem. 相似文献
