John Plamenatz Bentham once said that the two great 'engines' of reality are punishment and reward. And, to be sure, 'engineering' is a derivative of engine. Putting metaphor and etymology to gether I come up with 'constitutional engineering' as a title that conveys, first, that constitutions are like (somewhat like) engines, i.e., mechanisms that must 'work' and that must have an output of sorts; and, second, that constitutions are unlikely to work as intended unless they employ the engines of Bentham, i.e., punishments and rewards. Indeed, in much of this book I argue the case for conceiving and building constitutions as incentive-based structures. The title also indicates that the book is comparative. Indeed, it is 'very comparative'. The general idea is that by comparing we draw lessons from other countries. Right. However, and further, this work is 'systematically comparative' both in coverage and in method. In coverage because the arguments are drawn from, and extend to, all existing democratic forms; and in method because the analysis crucially relies on comparative control: all generalizations are checked vis-a-vis the cases to which they apply. The work is divided into three parts, namely, (i) Electoral Systems, (ii) Presidentialism and Parliamentarism, and (iii) Issues and Proposals. Electoral systems may not be formally included in the constitutional text and yet remain, in fact, a most essential part of the workings of political systems. Not only are electoral systems the most manipulative instrument of politics; they also shape the party system and affect the spectrum of representation. They are thus reviewed first. I overview proportional representation systems, the single member district system, and the various (little known or unduly neglected) double ballot formulas. Which are, in each ix Preface X case, the effects of any given system? It will be shown that the literature on electoral systems is often quite wrong in its causal analysis and also in its praises and blames. The Lijphart thesis that proportional representation is always better in that it is conducive to consensus democracy is untenable; the 'direct ness' of single member district systems is often dubious and must be related to 'localism'; the double ballot systems need not be majoritarian but can also apply to multi-member (if small) electoral districts. Part Two provides an underpinning of presidential versus semi-presidential systems. I propose definitions of both, single out the borderline cases (such as Finland), and then probe the conditions that indeed 'condition' the performance of presi dentialism and semi-presidentialism. Why does South-Amer ican presidentialism seldom work? And under what conditions does the American prototype work best? Assuming that undivided government is the major working condition of presidential systems, one must also consider party discipline (or, conversely, its lack) in Congress, the degree of opinion polarization, and other factors. As for French-type semi presidentialism, the major asset of its dual authority structure appears to be that the formula can cope with divided government. Part Two also discusses in detail the parliamentary systems largely a misnomer for a variety of fundamentally different formulas. The English system clearly is a premiership system; the German Kanzlerdemokratie is a controlled parliamentary system; whereas at the other end one finds assembly systems (the French III and IV Republic) whose working capabilities hinge on party discipline, on the degree to which parliaments are party-controlled. Here again, condition analysis is crucial. The English system hinges on a single-member district system which does produce single party government (a condition that fails to apply to India). The German formula presupposes a two-and-a-half party system, and can hardly be successfully extended and even less exported to four-five party systems. The Third Part illustrates - among other things - a new proposal, namely, a system of alternating or intermittent presidentialism that squarely confronts the straits of both the
