Is voluntary government possible? A critique of constitutional economics

According to public choice theory, the market and the state are both device s through which cooperation is organized and made possible. This theme of v oluntary government is most prevalent in the subset of public choice known as constitutional economics. We believe that the analogy between politics a nd markets made by constitutional economists is theoretically weak and clou ds rather than enhances our understanding of political economy. Politics ha s very little in common with non-coercive, voluntary exchange in the market place.
