Input: Read this: Hayek's influence on the development of economics is widely acknowledged. Hayek is the second-most frequently cited economist (after Kenneth Arrow) in the Nobel lectures of the prize winners in economics, which is particularly striking since his own lecture was critical of the field of orthodox economics and neo-classical modelisation. A number of Nobel Laureates in economics, such as Vernon Smith and Herbert A. Simon, recognise Hayek as the greatest modern economist. Another Nobel winner, Paul Samuelson, believed that Hayek was worthy of his award but nevertheless claimed that "there were good historical reasons for fading memories of Hayek within the mainstream last half of the twentieth century economist fraternity. In 1931, Hayek's Prices and Production had enjoyed an ultra-short Byronic success. In retrospect hindsight tells us that its mumbo-jumbo about the period of production grossly misdiagnosed the macroeconomics of the 1927–1931 (and the 1931–2007) historical scene". Despite this comment, Samuelson spent the last 50 years of his life obsessed with the problems of capital theory identified by Hayek and Böhm-Bawerk, and Samuelson flatly judged Hayek to have been right and his own teacher, Joseph Schumpeter, to have been wrong on the central economic question of the 20th century, the feasibility of socialist economic planning in a production goods dominated economy.
Question: On the topic of the practicality of a socialist economy, who does Samuelson believe was wrong?

Output: Joseph Schumpeter

Input: Read this: The constitution of Jordan grants its monarch the right to withhold assent to laws passed by its parliament. Article 93 of that document gives the Jordanian sovereign six months to sign or veto any legislation sent to him from the National Assembly; if he vetoes it within that timeframe, the assembly may override his veto by a two-thirds vote of both houses; otherwise, the law does not go into effect (but it may be reconsidered in the next session of the assembly). If the monarch fails to act within six months of the bill being presented to him, it becomes law without his signature.
Question: The constitution of Jordan does not grant the monarch the right to do what?

Output: unanswerable
