Seasonal asymmetries in wholesale–retail cost pass-through

This article investigates the extent of seasonal asymmetries in wholesale to retail cost pass-through in the Canadian apple market. We model nonlinearity in cost pass-through in a panel two-regime error correction model. The model employs weekly store-level retail matching wholesale price data for a major US retail chain. Our results reveal distinct seasonal asymmetries in cost pass-through. Retail prices adjust faster during the fall indicating significantly higher pass-through in response to a change in input composition and seasonal expansion of alternative marketing channels. This input composition effect on cost pass-through highlights the general importance of time-variant market conditions and their respective determinants in explaining cost pass-through dynamics in commodity markets.     

Interest rate pass-through in Morocco: Evidence from bank-level survey data

We investigate the relationship between banks’ marginal cost and retail lending rates in Morocco. The data covers the rates of new business loans for four market segments broken down by institutional sector between 2006Q2 and 2016Q4. We examine the pass-through mechanism using recently developed heterogeneous panel cointegration framework. Our findings suggest that there is a high degree of pass-through heterogeneity over bank products. The weak adjustment for short-term credit facilities and consumption loans can be explained by credit risk compensation allowing banks to reduce their exposition to systemic risks. Corporate loans are priced more competitive than household and individual entrepreneur products, suggesting that negotiation power or the competition from the borrower side matters. Overall, our results indicate that banking market contestability has improved during the last decade.     

Deregulating Network Industries: Dealing with Price-quality Tradeoffs

This paper examines the effects of introducing competition into monopolized network industries on prices and infrastructure quality. Analyzing a model with reduced-form demand, we first show that deregulating an integrated monopoly cannot simultaneously decrease the retail price and increase infrastructure quality. Second, we derive conditions under which reducing both retail price and infrastructure quality relative to the integrated monopoly outcome increases welfare. Third, we argue that restructuring and setting very low access charges may yield welfare losses, as infrastructure investment is undermined. We provide an extensive analysis of the linear demand model and discuss policy implications.     

Carbon tax pass-through in Canadian retail gasoline markets

A carbon tax's pass-through is one factor influencing its effectiveness in internalizing the externality created by greenhouse gas emissions. This paper measures the pass-through of carbon taxes introduced in retail gasoline markets of four Canadian provinces that did not meet the carbon pollution pricing federal benchmark stringency requirements. Those four provinces are Saskatchewan, Manitoba, Ontario and New Brunswick. Using daily retail gasoline prices for 40 treated cities and nine control cities we find the pass-through rates are city-specific and vary from 0% to over 140%. City-specific pass-through rates imply that estimations at a higher level of geographical aggregation assume homogeneous effects where heterogeneous effects might be present. Our results also suggest it would be difficult for a government to impose an optimal and nationwide carbon tax on automotive greenhouse gas emissions. Although the degree of competition can explain city-specific pass-through rates, it cannot explain over-shifting. Over-shifting can be explained, however, by the demand functional form.     

STORABLE GOOD MARKET WITH INTERTEMPORAL COST VARIATIONS

We investigate a firm's dynamic pricing policy in a storable good market where the cost of production varies over time. In anticipation of a cost increase, the firm selects its prices to affect consumer storage. Price dynamics hinge upon the curvature of demand and the magnitude of the consumer storage cost. When demand is not too convex, the consumers' reluctance to store leads the firm to reduce prices to stimulate consumer storage. This shapes the firm's cost pass-through and the price commitment effects. Our analysis provides a novel explanation for the well-documented puzzling patterns of incomplete and negative cost pass-through.     

Bank behavior, incomplete interest rate pass-through, and the cost channel of monetary policy transmission

This paper employs a New Keynesian DSGE model to explore the role of banks within the cost channel of monetary policy transmission for shaping the interest rate pass-through from money market rates to loan rates. Banks extend loans to firms in an environment of monopolistic competition by setting their loan rates in a staggered way, which means that the adjustment of the aggregate loan rate to a monetary policy shock is sticky. We estimate the model for the euro area by adopting a minimum distance approach. Our findings exhibit that (i) financial costs are an important factor for price changes, (ii) frictions in the loan market have an effect on the propagation of monetary policy shocks as the pass-through from a change in money market rates to loan rates is incomplete, and (iii) the strength of the cost channel is mitigated as banks shelter firms from monetary policy shocks by smoothing loan rates.     

Structural breaks in the lending interest rate pass-through and the euro

This paper investigates whether size and speed of the pass-through of market rates into short term business lending rates have increased in the wake of the introduction of the euro. Allowing for multiple unknown structural breaks we find two in four EMU countries, and in the UK as well, and a single one in five other countries. The pattern of dates fits national banking systems adjusting slowly to the new monetary regime and suggests caution in associating structural changes to the introduction of the euro. The estimated equilibrium pass-through in the last break-free period is on average more incomplete, hinting at a reduced effectiveness of the single monetary policy. These results run against the economic intuition that a reduced volatility in money market rates is bound to mitigate uncertainty and to ease therefore the transfer of policy rate changes to retail rates; the run-up to Basel 2 and a deterioration of competition in loan markets could be the motivations. Caution in extrapolating these findings to recent periods is suggested by the differences between the unharmonized and the new harmonized retail rates.     

Competition among banks and the pass-through of monetary policy

This paper introduces monopolistically competitive financial intermediaries into the New Keynesian DSGE setting. Modelling bank market power explicitly contributes to understanding two empirical facts: (i) The short-run transmission of changes in money market rates to bank retail rates is far from complete and heterogeneous. (ii) Stiffer competition among commercial banks implies that loan rates correlate more tightly with the policy rate. In my model, the degree of monopolistic competition in the banking sector has a sizeable impact on the pass-through of changes in the policy rate. In particular, a more competitive market for bank credit amplifies the efficiency of monetary policy.     

The empirical content of Cournot competition

We consider the testable implications of the Cournot model of market competition. Our approach is nonparametric in the sense that we abstain from imposing any functional specification on market demand and firm cost functions. We derive necessary and sufficient conditions for (reduced form) equilibrium market price and quantity functions to be consistent with the Cournot model. In addition, we present identification results for the corresponding inverse market demand function and the firm cost functions. Finally, we use our approach to derive testable restrictions for the models of perfect competition, collusion and conjectural variations. This identifies the conditions under which these different models are empirically distinguishable from the Cournot model. We also investigate empirical issues (measurement error and omitted variables) related to bringing our testable restrictions to data.     

The determinants of retail petrol prices in Greece

The purpose of this article is to examine the relationship between retail prices of petrol, international oil prices and tax rates in Greece. We examine not only the hypothesis that retail prices act asymmetrically to crude oil price changes and the pass-through rates of tax increases, but also use the cross-sectional dimension of the data to explore whether the existence or otherwise of market power affects retail prices. Our results provide little evidence for asymmetric behaviour. However, the degree to which prices overreact to tax changes and the significance of market power across the different regions suggests that the market for petrol/diesel is not very competitive.     

Price transmission and local market power: empirical evidence from the Austrian gasoline market

We analyse the impact of local market power on price margins and different dimensions of price adjustment dynamics (speed and asymmetry of price transmission) using data for a large number of individual gasoline stations in Austria. Specific attention is paid to threshold effects in price adjustment. Our results clearly suggest that the speed of price transmission between the Brent crude oil index and retail diesel prices is higher in a more competitive environment. While evidence on the relationship between local market power and asymmetries in the speed of price adjustment is mixed, our findings regarding asymmetries in price thresholds are clear: in regions where competition from neighbouring rivals is weak and/or consumers’ price elasticity of demand is low (stations located on the highway), positive thresholds significantly exceed negative ones, which corresponds to the ‘rockets and feathers phenomenon’. As expected, we observe that prices are lower in more competitive local markets.     

Protection for sale under monopolistic competition: Beyond the CES

We extend the protection for sale model of Grossman and Helpman (1994) by introducing a general model of monopolistic competition with variable markups and incomplete pass-through. We show that the structure of protection emerging in the political equilibrium not only depends on the weight attached by the government to consumer welfare when making its policy decision, but also on the degree of market power of firms and on the terms-of-trade variations due to the degree of pass-through. Our results highlight the importance of preferences in shaping the structure of protection and are consistent with the occurring of protectionism also in unorganized industries.     

Time lags in the pass-through of crude oil prices: big data evidence from the German gasoline market

This article investigates the pass-through of global Brent oil notations to fuel prices across the oligopoly of retail majors in Germany. We assemble a high-frequency panel data set that encompasses millions of price observations and allows us to distinguish effects by brand. Upon establishing a cointegrating relationship between fuel and crude oil prices using daily data, we estimate an ECM and find that (1) the pass-through of oil prices critically depends on the number of time lags included in the ECM; (2) strict adherence to classical information criteria for determining lag length yields extremely long pass-through durations and (3) the estimated impulse response functions are virtually identical across brands, irrespective of the lag count, suggesting a high degree of competition among brands.     

Exchange rate pass-through in the U.S. automobile market: A cointegration approach

This study analyzes exchange rate pass-through in the presence of monopolistic competition in the U.S. automobile market. Using cointegration techniques, we investigate how foreign competing firms' prices interact following an exchange rate-shock. The results generally indicate price interdependence (competition) among the rival firms. In one case where we did not find any price interdependence, the extent of exchange rate pass-through was higher. This validates the economic intuition that a low degree of price competition corresponds with a high degree of exchange rate pass-through.     

Banking market integration in the SADC countries: evidence from interest rate analyses

This study investigates the state, development and drivers of banking market integration in the member countries of the Southern African Development Community (SADC). A Principal Component Analysis (PCA) of national retail interest rates indicates increasing integration in loan and deposit markets. These integration processes are not developing uniformly and we can identify a convergence club. When investigating the interest rate pass-through from central bank onto retail rates for this convergence club, we find both, genuine and monetary-integration driven processes though the latter dominate. We thus conclude that a selective expansion of the Common Monetary Area (CMA) is possible.     

Exchange Rate Pass-Through in Vertically Related Markets

The paper provides a theoretical framework which addresses exchange rate pass-through within the setting of vertically related markets. In particular, foreign firms' price adjustment in response to an exchange rate shock is evaluated. This permits study of the importance of cost effects of the exchange rate shock. Recent empirical evidence indicated the relevance of these cost effects. It is shown that one can decompose the effects of an exchange rate shock on the final goods market into direct and indirect components. The indirect effect works through the input market. The degree of pass-through then depends on the relative importance of direct and indirect effects, which in turn depends on the nature of vertical structures and strategic firm behavior. It is shown that the institutional aspects of vertically related markets play a role in explaining incomplete price adjustments in both intermediate and final goods markets and the failure of PPP in the short run.     

Liberalization of Opening Hours with Free Entry

Abstract. This paper studies competition in prices and opening hours in a model with free entry. It is shown that under free competition market failures arise: Entry is excessive and opening hours are under‐provided. The larger the demand elasticity, the larger market failures are going to be. Restrictions on opening hours aggravate this failure. We analyze the impact of a liberalization of opening hours. The model predicts that prices will remain constant in the short run but increase in the long run. Concentration in the retail sector will rise. Additionally, employment in the retail sector increases.     

Determinants of Interest Rate Pass-through for Emerging Market Economies: The Role of Financial Market Structure

It is essential for central banks to assess whether or not the pass-through from monetary policy rates to credit and deposit interest rates is complete in order to ensure price stability. In this article, we analyze interest rate pass-through process for emerging market economies. Since emerging market countries lack large panel data sets that are typically available for developed countries, it is hard to analyze the determinants of pass-through coefficients for emerging market countries. To overcome the data issue, we developed a country selection procedure that minimizes heterogeneity among the countries included in the analysis. Our findings indicate that banking sectors?? competition plays a more important role for emerging market countries than their developed counterparts.     

Commodity taxes and welfare under endogenous market conduct

We consider consumption taxes in a model of endogenous Cournot versus Bertrand competition. It is argued that when the choice of unit versus ad valorem taxes affects longer-term decisions beyond the customary price or quantity decisions, the mix of the two taxes co-determines market conduct. This gives ad valorem taxes an anti-competitive effect that harms ad valorem taxes’ efficiency in comparison with unit taxes. We show that a mix of the taxes—or a unit tax alone if we compare one or the other of the taxes—is sometimes welfare superior on account of consumer-price and tax revenue effects. A practical implication of our findings is that pass-through rates are only sometimes useful guides for policy. In fact, we show when the proper response to demand for higher revenue is a higher unit tax rate and a lower ad valorem tax rate.
