I have never heard that the demand curve must be concave. In fact, it is most often modeled as either linear or convex. Common convex specifications include log-linear and constant-elasticity demand functions. A number of empirical papers attempt to estimate the shape of the demand curve for specific products but I am not familiar with anyone concluding that demand is concave generally.
The production possibility curve is not always linear, in fact, it is usually concave down (bowed-in). The shape of the curve depends on the substutability of the goods described by the curve in the question. When goods are perfectly substitutable in production, the PPP (or PPF) is linear.
other names for production possibility boundary are: production possibility curve production possibility frontier transformation curve.
The production possibility curve is an analytical tool that is u to explain,analyse and justify the problem as regards the choices in the allocation of productive resources to achieve a given level of output in an hypothetical way. It is based on a short run period is production where some factors are held constant and the otthers can be varied to achieve a given level of output. The production possibility curve explains the rate of transformation between commodity (x and y) when the level of productive resources is given.the slope of the curve is concave to the origin and it touches both axis. The production possibility curve is also called production frontier or production boundary.
The most common shape of a Production Possibility Curve (PPC) is a concave bulging in towards the origin (or a quarter circle from one axis to the other.) This is due to the fact that as the production in one goods increase, the opportunity cost of producing the extra of that good (or the amount of Good B that it has to give up) become less.

The Law of Increasing Opportunity Cost that is shown in a Production Possibilities Curve is concave to the origin. This is because it shows the maximum gain of two products used in production.

The PPF is bowed outwards (concave to the origin) as tradeoffs between the production of any two goods are constant.

production possibility curve
Production Possibility curves can assume different slopes. As far as i know it can be either concave, convex or a straight line. The concave curve would be concave and downward sloping.This is explained by the law of diminishing returns and that factors used are not homogeneous.In this case the Marginal Rate of technical substitution would be rising. The curve would be convex in case of rising productivity and decreasing opportunity cost. Finally it would be a straight line when factors are homogeneous. Hope it was helpfull. Akheel.
