How do capacity constraints affect the slope of the Phillips curve? In particular, do changes in output affect prices by more when firms face more strongly diminishing returns? Intuitively, one may conjecture that the answer is yes. With more strongly diminishing returns, marginal costs increase more when production increases, also raising prices by more. But this intuition is incomplete in models with sticky prices à la Calvo. In the standard New Keynesian model with Calvo pricing frictions, more strongly diminishing returns actually flatten the Phillips curve. The reason is the reluctance of firms who alter their prices to let their prices get too far out of line with the prices set by firms that do not adjust. We explain how the Phillips curve might be amended to avoid this implausible feature, for example, by using Rotemberg pricing or introducing wage stickiness.

Abstract In periods of distress, observed and perceived income risk tends to rise. Does this heightened income risk affect monetary transmission? This paper first shows that in partial equilibrium, heightened income risk dampens the substitution effect of interest rate changes but amplifies the indirect income effect of wage changes. The effects are sizable in partial equilibrium. An increase in income risk consistent with heightened risk during recessions affects interest rate and wage responses by around one‐third. However, because income risk dampens the effects of interest rate changes but amplifies the effects of wage changes, its effect is weaker in general equilibrium, dampening monetary transmissions to consumption by around 11 percent.

We use sizable lottery prizes in Norwegian administrative panel data to explore how transitory income shocks are spent and saved over time, and how households’ marginal propensities to consume (MPCs) vary with household characteristics and shock size. We find that spending peaks in the year of winning and gradually reverts to normal within five years. Controlling for all items on households’ balance sheets and characteristics such as education and income, it is the amount won, age, and liquid assets that vary systematically with MPCs. Low-liquidity winners of the smallest prizes (around USD 1,500) are estimated to spend all within the year of winning. The corresponding estimate for high-liquidity winners of large prizes (USD 8,300-150,000) is slightly below one half. While conventional models will struggle to account for such high MPC levels, we show that a two-asset life-cycle model with a realistic earnings profile and a luxury bequest motive can account for both the time profile of consumption responses and their systematic co-variation with observables.

We provide the analytical explanation of the interactions between precautionary saving and liquidity constraints. The effects of liquidity constraints and risks are similar because both stem from the same source: a concavification of the consumption function. Since a more concave consumption function exhibits heightened prudence, both constraints and risks strengthen the precautionary saving motive. In addition, we explain the apparently contradictory results that constraints and risks in some cases intensify, but in other cases weaken the precautionary saving motive. The central insight is that the effect of introducing an additional constraint or risk depends on whether it interacts with preexisting constraints or risks. If it does not interact with any preexisting constraints or risks, it intensifies the precautionary motive. If it does interact, it may reduce the precautionary motive in earlier periods at some levels of wealth.

We provide a new estimate of household-level housing wealth in Norway between 1993 and 2015 using an ensemble machine learning method on housing transaction data. The new housing wealth measure is an improvement over existing data sources for two reasons. First, the model outperforms previously applied regression models in out-of-sample prediction precision. Second, we extend the sample of estimated housing wealth by including cooperative units, non-id apartments, and cabins.

We investigate the transmission of monetary policy to household consumption using administrative data on the universe of households in Norway. On the basis of identified monetary policy shocks, we estimate the dynamic responses of consumption, income, and saving along the liquid asset distribution of households. For low-liquidity but also for high-liquidity households, changes in disposable income are associated with a sizable consumption reaction. The impact consumption response is closely linked to interest rate exposure, which is negative at the bottom but positive at the top of the distribution. Indirect effects of monetary policy gradually build up and eventually outweigh the direct effects.

How do liquidity constraints affect households? This is a well-researched subject with remarkably few theoretical results. This paper bridges this gap by providing a closed form expression for consumption with liquidity constraints for a wide class of utility functions (HARA). Using this expression, I prove that the consumption function is strictly concave in wealth if a relevant liquidity constraint exists. Moreover, households respond to a tightening of the liquidity constraint by reducing consumption, becoming more sensitive to wealth changes, and having a “more” concave consumption function in wealth. These results thus provide theoretical underpinnings for how contractions in credit supply affect households

We estimate local government spending multipliers using administrative data on municipalities in Norway. Based on identified shocks we estimate the dynamic response of gross production across geographical units and sectors of the economy. We find that the multipliers increase with the home bias in consumption. The results indicate that spending multiplier is closely linked to import leakages, which are reduced as the size of the economy increases. We observe that the public sector is the first to be affected by public spending, before the multiplier builds up in the private sector. We also show that similar results can be obtained by using a structural vector autoregressive models (SVAR) with various identifying assumptions.

Denne rapporten er skrevet på oppdrag for Sysselsettingsutvalget. Sysselsettingsutvalget skal analysere utviklingen i sysselsettingen i Norge og foreslå tiltak for å øke sysselsettingen. Arbeidet er delt opp i to faser. Fase én var ferdig da ekspertgruppen la fram sine forslag for økt sysselsetting 28. mars 2019. I fase to er utvalget utvidet og inkluderer partene i arbeidslivet. Fase to begynte 5.april 2019. I denne rapporten analyseres hvordan markedsmakt og ulikhet kan påvirke den økonomiske aktiviteten, herunder sysselsettingen.

We exploit a school reform that increased the length of compulsory schooling in Norway in the 1960s to study the causal effect of formal general education on returns on wealth (k-returns). OLS estimates reveal a strong, positive and statistically significant correlation between education and returns on individual net worth. This effect disappears in IV regressions, implying that general education has no causal effect on individual performance in capital markets, whose heterogeneity largely reflects non-acquired ability. On the contrary, we find that education causes higher returns in the labor market (l-returns). We speculate about possible rationales for this important asymmetry.
