Project Description

Summary: Despite the implications for policy, empirical evidence on the relative importance of factors that shape labor supply responses is missing. This paper helps fill this gap and quantifies the role of information frictions vs. other frictions by combining notches in the Norwegian welfare system and quasi-experimental variation in access to information about the slope and location of kinks. While we estimate a frictionless elasticity of 0.3, overall frictions attenuate this elasticity by about 70 percent. We find the information letter increased the earnings elasticity from 0.06 to 0.15, implying that information frictions account for at least 30% of total attenuation.

Subject Terms: labor

JEL Classification:
      H20 Taxation, Subsidies, and Revenue: General
      H31 Fiscal Policies and Behavior of Economic Agents: Household

Geographic Coverage: Norway

Time Period(s): 1993 – 2016

Collection Date(s): 2015 – 2016

Universe: All disability insurance recipients registered i) over the period 1993 to 2014 and ii) at January 1st, 2015. We then follow their income and work history from 1993 to 2016.

Data Type(s): administrative records data

Collection Notes: The data employed in the analysis are drawn from Norwegian administrative registers. Researchers can gain access to the data by submitting a written application to the data owners. Applications must be certified by The Norwegian Data Inspectorate in order to ensure that data are processed in a manner that protects the personal integrity of individuals surveyed. Conditional on this approval, Statistics Norway will then determine which data one may obtain in accordance with the research plan. Inquiries about access to data from Statistics Norway should be addressed to: [email protected]. More information is available at https://www.ssb.no/en/omssb/tjenester-og-verktoy/data-til-forskning

Methodology

Data Source: We use the administrative data source called "a-ordningen" that covers monthly income from matched employer-employee data from 2015 to 2016. We also use tax register files to capture annual income and labor earnings over the period 1993 to 2015. Population panel data fra Statistics Norway provides us with information on education (NUDB), gender and age (Befolkningsfiler).

There were two data sources used from the Norwegian Welfare Administration (NAV). The first covers all disability insurance recipients in 2015. The second provides us with records on whether a person received the information letter.
