Description

Data from a study on Western European government formation duration. Data is at the country-level (N = 409). Variable names are taken directly from original dataset. The data is publicly available and has been included here with the endorsement of the author. Please see the original codebook for a more detailed description of the variables.

Usage

data(govtform)

Format

A data frame with 410 rows and 18 variables. The following are taken from the codebook at 10.7910/DVN/BUWZBA.

countryname

names of countries used in analysis

country

unique number identifying each country

cabinet

bargainingdays

the number of days between either an election or the resignation of the previous government and the day on which the new government is officially inaugurated

datein

date on which a government took office. Format is YYMMDD

dateout

date on which a government left office. Format is YYMMDD

postelection

dichotomous variable that equals 1 if a government is the first to form after an election (more uncertainty) and 0 if it forms in an interelection period (less uncertainty)

nonpartisan

dichotomous variable that equals 1 if the government is nonpartisan and 0 otherwise

legislative_parties

a fraction representing the number of parties that have won legislative seats. See codebook for more detail

inconclusive

the number of inconclusive bargaining rounds prior to a new government successfully forming

cabinetname

cabinet name identified by surname of prime minister (followed by a number if the PM presided over more than one cabinet)

singleparty_majority

dichotomous variable that equals 1 if a single party controls a majority of the legislative seats, 0 otherwise

polarization

measures the level of ideological polarization in the party system. See codebook for more detail

continuation

dichotomous variable that equals 1 if the outgoing government or formateur gets the first opportunity to form a new government, 0 otherwise. See codebook for more detail

positive_parl

dichotomous variable that equals 1 if a new government requires the explicit support of a legislative majority in order to take office, 0 otherwise. See codebook for more detail

post_legislative_parties

interaction term made by multiplying the postelection variable with the legislative_parties variable

post_polariz

interaction term made by multiplying the postelection variable with the polarization variable

post_positive

interaction term made by multiplying the postelection variable with the positive_parl variable
