Abstract

Political scientists typically develop different models to examine distinct political phenomena such as lobbying, protests, elections and conflict. These specific models can provide important insights into a particular event, process or outcome of interest. This article takes a different tack. Rather than focus on the specificities of a given political phenomenon, this study constructs a model that captures the key elements common to most political situations. This model represents a reformulation and extension of Albert Hirschman’s famous Exit, Voice and Loyalty framework. To highlight the value that comes from focusing on the commonalities that exist across apparently disparate political phenomena, the article applies the model to several issues in the democratization literature related to modernization theory, the political resource curse, inequality, foreign aid and economic performance.

Fig. 1EVL game Note: E is the citizen’s exit payoff, 1 is the value of the benefit that the government takes from the citizen in the pre-history of the game, L is the value the government obtains from having a loyal citizen who does not exit, and c is the citizen’s cost of using voice. It is assumed that c, L>0.

Fig. 2Extended EVL game Note: E is the citizen’s exit payoff, 1 is the value of the benefit belonging to the citizen at the beginning of the game (and which the government is deciding whether to take), L is the value the government obtains from having a loyal citizen who does not exit, c is the citizen’s cost of using voice and cg is the cost to the government imposed by the citizen’s use of voice. It is assumed that c, cg, L>0, and that E<1.

Fig. 3EVL democratization game Note: the game comprises two players: the citizen and the government. The citizen’s payoffs depend on her pre-tax income from the first best use of her asset, Y; the expected return on the second best use of her asset, E; her discount factor, δ; the cost of objecting to the government’s tax hike, c; and whether the tax rate is low, τL, or high, τH. The government’s payoffs depend on the citizen’s pre-tax income from the first best use of her asset, its discount factor, and the tax rate. It is assumed that τH>τL≥0, and that $0\,\lt\,c\leq \left( {\tau _{H} {\minus}\tau _{L} } \right)Y{\plus}\mathop{\sum}\nolimits_{t{\equals}1}^\infty {\delta ^{t} \left[ {\left( {1{\minus}\tau _{L} } \right)Y{\minus}E} \right]} $.
