More Facts about Prices: France Before and During the Great Recession

Using microprice data, we document new facts on price rigidity in France: (i) each month 20.1% of prices are changed, which compares to 24.1% in the United States—excluding sales, however, the fraction of prices modified each month is about the same in France and in the United States (around 17%); (ii) the distribution of price changes is quite dispersed; (iii) the frequencies of price increases and decreases contribute a lot to inflation variations, and price increases are more frequent in January (even when sales are excluded); (iv) sales contribute significantly to the volatility of inflation but play a minor role in the transmission of macroeconomic fluctuations to prices; and (v) during the Great Recession patterns of price adjustment were only slightly modified.     

Price Setting in the Euro Area: Some Stylized Facts from Individual Producer Price Data

This paper summarizes the microevidence on the setting of producer prices in the euro area. The main findings are: (i) 21% of producer prices are adjusted each month, (ii) producer prices are changed more frequently and by smaller amounts than consumer prices (even after controlling for product characteristics), (iii) price decreases are relatively frequent, (iv) inflation correlates positively with the difference between the frequency of price increases and decreases, and (v) there is substantial variation in price flexibility across sectors, which can be explained in part by differences in the cost structure, the degree of competition, and the level of sectoral inflation.     

Corporate Governance and Capital Structure Dynamics

We develop a dynamic tradeoff model to examine the importance of manager–shareholder conflicts in capital structure choice. In the model, firms face taxation, refinancing costs, and liquidation costs. Managers own a fraction of the firms’ equity, capture part of the free cash flow to equity as private benefits, and have control over financing decisions. Using data on leverage choices and the model's predictions for different statistical moments of leverage, we find that agency costs of 1.5% of equity value on average are sufficient to resolve the low‐leverage puzzle and to explain the dynamics of leverage ratios. Our estimates also reveal that agency costs vary significantly across firms and correlate with commonly used proxies for corporate governance.     

Stock Returns in Mergers and Acquisitions

This paper develops a real options framework to analyze the behavior of stock returns in mergers and acquisitions. In this framework, the timing and terms of takeovers are endogenous and result from value-maximizing decisions. The implications of the model for abnormal announcement returns are consistent with the available empirical evidence. In addition, the model generates new predictions regarding the dynamics of firm-level betas for the period surrounding control transactions. Using a sample of 1,086 takeovers of publicly traded U.S. firms between 1985 and 2002, we present new evidence on the dynamics of firm-level betas, which is strongly supportive of the model's predictions.     

Restaurant Prices and the Minimum Wage

In this paper, we examine the effect of the minimum wage on restaurant prices. We contribute both to the study of economic impact of the minimum wage and to the study of microeconomic patterns of price stickiness. For this purpose, we use a unique data set of individual price quotes collected to calculate the Consumer Price Index in France and we estimate a price rigidity model based on a flexible rule. We find a positive and significant impact of the minimum wage on prices. The effect of the minimum wage on prices is, however, very protracted. A change in the minimum wage takes more than a year to fully pass through to retail prices.     

The Dynamics of Gasoline Prices: Evidence from Daily French Micro Data

Using millions of individual gasoline prices collected at a daily frequency, we examine the speed at which market prices of refined oil are transmitted to retail gasoline prices in France. For that, we estimate a reduced‐form model of state‐dependent pricing where thresholds triggering price changes are allowed to vary over time and depend on the duration since the last price change. We find that the degree of pass‐through of wholesale prices to retail gasoline prices is on average 0.77 for diesel and 0.67 for petrol and depend on local market characteristics. The duration for a shock to be fully transmitted into prices is about 10 days. There is no significant asymmetry in the transmission of wholesale price to retail prices. Finally, the duration since the last price change has a significant effect on thresholds triggering price changes but a large variance of idiosyncratic shocks on thresholds is also crucial to replicate the size distribution of price changes.
