Sectoral Inflation Dynamics, Idiosyncratic Shocks and Monetary Policy

This paper disentangles fluctuations in disaggregate prices into macroeconomic and idiosyncratic components using a factor-augmented vector autoregression (FAVAR) in order to shed light on sectoral inflation dynamics in Switzerland. We find that disaggregated prices react only slowly to monetary policy and other macroeconomic shocks, but relatively quickly to idiosyncratic shocks. We document that there is a large heterogeneity across sectors in the reaction to monetary policy shocks and show that sectors with larger volatility of idiosyncratic shocks react more readily to monetary policy. This finding stands in contrast to the rational inattention model of price setting. We also find that sectors, which change prices infrequently, react less strongly but if they do change their prices, they adjust them by a large amount. This suggests that the source of sluggish response to aggregate shocks is heterogeneity in menu costs rather than rational inattention. Furthermore, even though prices respond with a significant delay to identified monetary policy shocks, we find no evidence of a price puzzle on average. For single sectors, however, we still find a hump-shaped response which can partially be explained by the fact that, by law, rents are tied to interest rates in Switzerland.monetary policy transmission, idiosyncratic shocks, rational inattention, heterogeneity in price setting, cost channel, price puzzle

Capacity Utilisation, Constraintes and Price Adjustments under the Microscope

This paper analyses the interplay of capacity utilisation, capacity constraints, demand constraints and price adjustments, employing a unique firm-level data set for Swiss manufacturing firms. Theoretically, capacity constraints limit the ability of firms to expand production in the short run and lead to increases in prices. Our results show that, on the one hand, price increases are more likely during periods when firms are faced with capacity constraints. Constraints due to the shortage of labour, in particular, lead to price increases. On the other hand, we also find evidence that firms are not reluctant to reduce prices in response to demand constraints. At the macro level, the implied capacity-utilisation Phillips curve has a convex shape during periods of excess demand and a concave shape during periods of excess supply. Our results are robust to the inclusion of proxies for changes in costs and the competitive position of firms.price setting, capacity utilisation, capacity constraints, demand constraints,non-linear Phillips curve, Switzerland

Do Prices in the EMU Converge (Non-linearly)?

This paper examines the current state of price convergence amongst the eleven initial EMU member states. Special attention is given to possible changes in the convergence process during the euro cash changeover. We apply the sigma-convergence approach using both panel estimates of changes in the deterministic time trend of a coefficient of variation and stochastic kernel-density estimates. We find that convergence took place before 2000, slowed down substantially between 2000 and 2003, and resurfaced after 2003. This points to a non-linear convergence path. We show that stronger convergence is associated with periods of positive and less-dispersed output gaps across member states. There are no big differences between the results for tradables and non-tradables, indicating that Balassa-Samuelson effects are relatively weak.Prices, European Monetary Union, Sigma-convergence, Kernel-density Estimation, Balassa-Samuelson Effect

Endogenous Product Adjustment and Exchange Rate Pass-Through

We document how product quality responds to exchange rate movements and quantify the extent to which these quality changes affect the aggregate pass-through into export prices. We analyze the substantial sudden appreciation of the Swiss franc post removal of the 1.20-CHF-per-euro lower bound in 2015 using export data representing a large share of the universe of goods exports from Switzerland. We find that firms upgrade the quality of their products after the appreciation. Furthermore, they disproportionately remove lower-quality products from their product ranges. This quality upgrading and quality sorting effect accounts for a substantial share of the total pass-through one year after the appreciation. We cross-check our results with the microdata underlying the Swiss export price index, which includes an adjustment factor for quality based on firms' reported product replacements, and obtain similar results

Microeconometric evidence on demand-side real rigidity and implications for monetary non-neutrality

To model the observed slow response of aggregate real variables to nominal shocks, most macroeconomic models incorporate real rigidities in addition to nominal rigidities. One popular way of modelling such a real rigidity is to assume a non-constant demand elasticity. By using a homescan data set for three European countries, including prices and quantities bought for a large number of goods, in addition to consumer characteristics, we provide estimates of price elasticities of demand and on the degree of demand-side real rigidities. We find that price elasticities of demand are about 4 in the median. Furthermore, we find evidence for demand-side real rigidities. These are, however, much smaller than what is often assumed in macroeconomic models. The median estimate for demand-side real rigidity, the super-elasticity, is in a range between 1 and 2. To quantitatively assess the implications of our empirical estimates, we calibrate a menu-cost model with the estimated super-elasticity. We find that the degree of monetary non-neutrality doubles in the model including demand-side real rigidity, compared to the model with only nominal rigidity, suggesting a multiplier effect of around two. However, the model can explain only up to 6% of the monetary non-neutrality observed in the data, implying that additional multipliers are necessary to match the behavior of aggregate variables

Tracking Inflation on a Daily Basis

Using online data for prices and real-time debit card transaction data on changes in expenditures for Switzerland allows us to track inflation on a daily basis. While the daily price index fluctuates around the official price index in normal times, it drops immediately after the lockdown related to the COVID19 pandemic. Official statistics reflect this drop only with a lag, specifically because data collection takes time and is impeded by lockdown conditions. Such daily real-time information can be useful to gauge the relative importance of demand and supply shocks and thus inform policymakers who need to determine appropriate policy measures

Employment Adjustment and Financial Constraints - Evidence from Firm-level Data

Firms adjust their employment to changes in output. But they tend to adjust it only partially. Typically, labor is hoarded in downturns and subsequently rms have to hire less in upturns. Investment in labor hoarding may therefore be in uenced by factors that impede investments, such as nancial constraints. Using rm-level data, we show that nancial constraints increase the sensitivity of employment to  uctuations in output considerably. When output changes, nancially constrained rms resize their labor force substantially more than rms that have abundant funding. Limited internal funding opportunities turn out to be just as important as the reduced access to external nance. The strongest impact, however, is observed when internal and external constraints occur jointly. In that case, rms lay o two-and-a-half times more employees than unconstrained rms. The amplifying eect of nancial constraints is similar in upturns and downturns, implying that nancially constrained rms not only reduce their workforce more when demand decreases, but they also hire more labor when demand increases

Employment Adjustment and Financial Tightness - Evidence from Firm-level Data

Firms tend to only partially adjust their workforce to changes in output. Typically, labour is hoarded in downturns; subsequently, firms have to hire less workers in upturns, but they can do so only if they can bear the current costs of keeping superfluous workers so that the firms can save rehiring costs in the future. Therefore, labour hoarding can be seen as an investment and may be influenced by factors, such as the firms' financial shortages, that tend to impede investments. Using Swiss firm-level data, we show that for firms in financially strained situations, the sensitivity of employment to fluctuations in output increases considerably. When output changes, financially tighter firms resize their labour force more than firms that have abundant funding. Both limited internal funding opportunities as well as the reduced access to external finance are important. The strongest impact, however, is observed when internal and external financial tightness occur jointly. In that case, compared to firms that are not in a financially strained situation, firms in a financially strained situation lay off twice as many employees. The amplifying effect of financial tightness is similar in upturns and downturns, implying that financially tight firms not only reduce their workforce more when demand decreases but also hire more labour when demand increases

Exchange rate and foreign GDP elasticities of Swiss exports across sectors and destination countries

This article uses a detailed breakdown of Swiss trade flows to identify how the impact of the two main determinants of Switzerland’s exports – foreign demand and the real exchange rate – varies across sectors and export destinations. Our main findings are that (i) both foreign demand and exchange rate elasticities vary substantially across both export sectors and export destinations. (ii) Foreign demand trends are more important for structural considerations than the exchange rate. This is due to the fact that exports of the two largest export sectors are relatively sensitive to long-run foreign demand developments while they are relatively insensitive to changes in the exchange rate. (iii) The sectoral structure of Switzerland’s exports has shifted towards goods that have a lower short-run demand elasticity and a higher long-run demand elasticity. Goods exports are thus less influenced by business cycle fluctuations while they benefit more from long-term growth trends. (iv) The export share of sectors with a relatively low exchange rate elasticity has increased. However, this result is mainly driven by the strong rise in exports of chemicals and pharmaceuticals as well as precision instruments and watches, which are also the two important sectors responsible for the Swiss trade surplus
