Yugoslavia was a very heterogeneous, so proper answer would be impossible. Instead, I'll just point out few trends that mostly apply to entire Yugoslavia, both the developed republics like Slovenia and underdeveloped ones like Macedonia. Also, I'll concentrate on immediate post-war decade.

At the beginning of Second world war, Yugoslavia was dominantly agrarian (some 80% of population, much more in south) and largely illiterate society. War was highly destructive in every sense, a bit over 1 milion were killed out of population of some 17 milion, most of transport infrastructure was destroyed, along with many homes and much of the industry. Without large UNRAA aid, there would be starvation, and without its trucks and rolling stock the country would hardly be connected at all.

However, there was a dominantly optimistic and future oriented outlook. Obviously it came from socialist ideas (although, explicit socialist rhetoric is rare before 1947 or 1948), but it applied to most. Through large mobilization of largely volunteer labour, with some forced labour, reconstruction and initial industrialization were completed very quickly, in few years. Agricultural output grew more slowly, it was not a focus, and reached its pre-war output only by the end of 1950s.

Most prominent trends of post-war were than rapid industrialization, along with urbanization and an enormous expansion of education at all levels, available to more people than ever before. Large movements from countryside to cities, and between poorer and more fertile lands did pose a significant stress on traditional societies. But at the same time, agricultural overpopulation was a century old problem at least, and it was significantly relieved.

In countryside, at the end of war and immediately after there was a strict land maximum so large landowners (individuals and institutions such as Churches) lost out, but for most a principle of "land belongs to those that till it" was applied. At the same time, prices of agricultural products were low, and compulsory sales to the state high. There was a brief but intensive collectivization campaign in 1949, but it was quickly abandoned. It was less violent and in parts more successful than comparative campaigns in most socialist states. In large part, it was because many people got their land either from that expropriated with imposition of land maximum, or confiscated from former enemies, including large Volksdeutscher community in fertile Vojvodina. Those were more open to collectivization of their newly acquired land.

In the mid 50s economic policy was reoriented to provide more consumer goods and to lighter industry. Before that, consumer goods were often hard to come by, but prevailing mood was of obvious progress and goal oriented. As people could, often for the first time, send their children to school, get employment, etc. improvements were often immediately visible.

For the agricultural side, I can recommend Fitzpatrick, Peasants and communists, for more on economy and its role in society Woodwart Socialist Unemployment.
