Marcus Noland, "Explaining Middle Eastern
Authoritarianism." The paper uses a series of statistical models to
parse competing explanations for why Arab political regimes are both
unusually undemocratic and unusually stable. The democratic deficit is
comprehensible in terms of underlying structural factors: lack of
modernization, British colonial history, the democratic status of
neighboring countries, reliance on taxes for government finance, and the
Arab population share. Interpretation of the last variable is
problematic: it could point to some essential anti-democratic aspect of
Arab culture, though the small existing body of survey evidence does not
appear to bear this out. Alternatively it could be a proxy for some
unobservable such as investment in institutions of internal repression
that may not be culturally determined and instead reflect elite
preferences. As interesting as the hypotheses which received
statistical support are the one that did not, including the presence of
oil rents, the status of women, conflict with Israel or other neighbors,
or Islam.
 
With respect to the likelihood of liberalizing political transitions,
the models indicate that the odds on these occurring in any given year
are generally low-on the order of 5-10 percent in any given year-but
rising, as increasing levels of income and education erode popular
acquiescence to authoritarian governance. In this respect, the
distinction between the interpretation of the Arab ethnic share as an
intrinsic cultural marker and as a proxy for some unobservable is
important-if the former is correct, then one would expect the likelihood
of regime change to rise only gradually over time whereas if it is the
latter the probabilities may exhibit much greater temporal variability.
 
That said, the specific recent democratizing episodes in Iraq, Lebanon,
and Palestine, collectively labeled "the Arab Spring," each have
strongly idiosyncratic elements. Nevertheless, the advent of pan-Arab
media, such as the television stations al-Jazeera and al-Arabiya, may be
contributing to a more genuinely pan-Arab cultural space in which
developments in one country have a more immediate and profound influence
on outcomes elsewhere within the region.
